[@Lugubrious] I'm not opposed to you guys getting inside while the drawbridge is still up but you would have to use abilities that would be unavailable to a OoT Link player as this game would be designed so that he could only get in while the bridge is open. The whole thing with the chain would be theoretically possible for Link to pull off with the hookshot so...

Link's tiny compared to Birdie, with minimal upper body strength.  The hookshot can only latch onto predetermined hookshot spots, whereas Birdie's chains can wrap themselves securely around whatever targets Birdie throws them at.  I'd say this isn't something Link can do in the game.
