I ran into this at 5 am, got interested, rolled some dice, and now I feel obligsted to flesh out this gigachad of a pilot
I'll get to work, for now here's what I got in an unorganized manner (let me know if I did anything wrong)

Experienced pilot
You have a somewhat higher chance to succeed in your actions, but a somewhat lower chance of synchronizing with your Framewerk. You may also roll for (or pick) one more Primary Weapon System, three more Secondary Systems, and one more Perk in addition to the default selection.

Background potential:
Supporter: You are an expert when it comes to providing assistance to others. While not flashiest role, you provide an essential duty, and become and anchor that the other pilots in the squad will rally behind when the going gets tough. You may receive an Additional Secondary System for your Framewerk. As a free action, you can use one of your Secondary Systems to assist one nearby ally once per turn. You may also perform a free reaction shot with your Primary Weapon at one enemy who performs an attack or move at medium range (think assault rifle range as a human equivalent). However, you tend to brush aside or even forget your own needs, putting others before you, sometimes to a worrying degree.

Perks
Athletic: You're a pinnacle of human physique, capable of running a marathon or wrestling a bear. You may even have competed in sports, earning gold medals. Your Framewerk piloting also gets some benefit, like increased speed of a lower weight class and stronger melee attacks of a heavier weight class.
Book Smart: You are knowledgeable and well-read in one subject of your choosing.

Framewerk Class
Very Heavy: Very Heavies are brutes, and their steps can cause the ground to tremble for a fair distance. You are to be respected and feared.
Type: Backliner: Your Framewerk is all about ranged superiority, and taking the enemy out before they can reach you. Whether it is precision elimination with a sniper rifle, covering fire with Gatling guns and flak cannons, or blowing them up to smithereens with a tactical artillery strike. You could even more experimental energy-based weaponry like lightning guns to zap your foes. 


Primary system
Dual Acid Cannons: These cannons fire detonating rounds that cause wide-spread, highly explosive acid damage. The corrosive payload can melt through armor and cause notable damage over time. Combined with the weapon's high rate of fire, the weapon is most effective against multiple targets.
Artillery Mortars: Cannon weapons mounted on the shoulders that fire explosive shells with high destructive yield. The weapon includes a projectile flight path calculation system that predicts the arcing paths of shells before they are fired from the weapon, improving accuracy. Weather and the movement of enemy units is not taken into account by the system's calculations. The weapon is intended devastation in a large are of effect. The cannon barrels are also modified to extend or shorten in length to allow better control over operational range. Includes several modes. During "Artillery Mode", the cannons are both extended and angled within 45 degrees from horizontal over the shoulders to allow for long-range bombardment. During "Mortar Mode" the cannons are shortened and within 45 degrees of being vertical to allow for rapid bombardment at medium ranges. Finally, during "Direct Mode" the cannons are angled almost entirely horizontal over the shoulders to allow for direct fire at shorter ranges. The weapon includes an assortment of shells available for use that can be switched out by pilot commands. Both mode and ammunition changes can be done once per turn.
HEFI Shell: High-Explosive Fragmentation Incendiary shells, shortened to HEFI, are more dangerous to use at shorter ranges due to the fragmentation and incendiary effects of the shells. These shells have a more pronounced arc, and are recommended for use in either Artillery or Mortar Mode.
APHE Shell: Armor-Piercing High-Explosive shells are designed for short to long range engagements. These shells have a less pronounced arc that allows for greater range, and are especially effective in Direct Mode due to possessing a smaller explosion radius.
HYDRA Shell: Specially designed shells that break apart and separate in midair, releasing a swarm of explosive capsules that carpet bomb over a targeted area. Recommended for use in Mortar Mode, cannot be used in Direct Mode. These shells must be carefully loaded, and therefore require more time to be loaded.
Titan Shell: Shells fitted with with large-yield conventional explosive warheads, resembling the detonation size and strength of a Massive Ordinance Air Blast (MOAB). Recommended only for Artillery Mode, as the explosion radius is large. Cannot be used in Direct Mode.

Secondary system:
Bastion: A portable wall capable of expanding and digging in to the ground to protect two adjacent ally Framewerks of Heavy weight class or smaller at each side. It is made using Carbonox and other advanced alloys, and highly resistant to plasma. In it's folded form it can be used as a battering ram or as a protecting armament against flanking opponents.
Energy Wings: Detachable energy fields that can take a multitude of shapes and block incoming strikes and projectiles. These can be used to guard the Framewerk from a variety of incoming attacks. However, they can travel a short distance away from the Framewerk and protect an ally as well.
Utility Drones: Your Framewerk's shoulders are enlarged and capable of releasing one drone each. While not as efficient or numerous as other types of drones, these drones can fly swiftly and perform a single role of your choosing including fire support, repairs, protection, surveillance or data gathering, and are equipped to serve that role. The two drones can have different roles.
Segmented Recombination: The Framewerk's construction is uniquely divided, with every single segment beyond the core, where the cockpit is located, capable of splitting off the core, and subsequently reattach with ease using magnetic forces. The divided parts can operate autonomously with inbuilt computer systems. As a result, the pilot can adapt to the increasing damage that the Framewerk can sustain during battle.
Power Engine: Mounted on the Frame's back, it is a power-increasing device that increases speed equal to one lower level of weight class, and power equal to a level of higher weight class. It also improves carrying capacity, allowing the Framewerk to lift up and carry ally Framewerks as a free action for that turn. The device needs to recharge for one turn before it can be used again.
