I have a Star Wars centric dice/stat system I can show you if you want to include it, just a suggestion if you want to consider that path.  

How will equipment be organized?  We could have a list of items, with prices and make players buy their things.  That way they could have a starting "allowance" to equip their characters, and people aren't all rocking the biggest baddest armor sets right out of the gate.  It would make earning money meaningful, too. Not to push the stat idea, but having fluid equipment would work well with that as well.  

I think that a period of turmoil would work particularly well for the setting you seem to be going for.  Maybe Ep IV, rebellion period?  Or else Old Republic, then we have the Sith running about as well.  

A basic CS could go like this:

Name: Obvi
Age: Whatever's appropriate for their species
Species: Obvi as well
Appearance: Do you like pictures or descriptions? 
Affiliation: I don't know if this is necessary, actually.  If everyone's in the guild. 
Background: Why the heck do they hunt bounties?
Equipment: What the heck do they hunt bounties [i]with[/i]?
Abilities: What the heck skills allow you to hunt bounties?  Let's limit this to four, and include their combat proficiency.  
Credits: How many you got?

We can throw personality into it if you like, but I find most people reveal it IC.
