Put the TIE Wings on the X-Wing body..how kewl would that be!
Build a droid compatible figures....create a half C-3PO and half Han Solo!
But it won't even be anything that fun. Probably a new scale. They love new sizes...let's make 3 FORCE BATTLERS a different scale from the originals and never go beyond that. Afterall, they are just for some toddler to smash in to the floor. Or GI JOE RETALIATION, 10" figures...two of them...both heroes and they are supposed to....? That's right, be smashed into things by a toddler.
I must've been a weird kids because I preferred things at least close to the same size. I had one 12" Star Wars figure I never really did anything with, it was cool...but i didn't play out GIANTS ATTACK stories too much.
