Battle Droid (weak, to me anyway) - STAP
Destroyer Droid (better)
not much, they hit all of them really. Unleashed Clegg
Old Ben, hood up, not much different from young Ben already done
Chewbacca - presumably in progress
Droids? - R2 & 3PO? Gotta be a way to do that. Could certainly do a flying version of R2, though that may be considered Episode II-ish
Stormtrooper - getting blown backwards from Han's blaster
Snowtrooper - running on Hoth and firing blaster
Scout trooper - on speeder bike - heck, do a three pack as suggested above or three interlocking individual pieces with Endor Luke and Leia plus the scout
Tie Pilot - if they can do something with Luke X-wing, maybe they can pull this off
Tarkin - I'd love to see this. If they can do the bust and make it cool, they could do this too.
Luke - X-wing already rumoured; Bespin would be mighty cool with a removable hand; Jedi Luke on the sail barge/skiff; Hoth Luke with Wampa as a two pack
Other Jedi: Plo Kloon or Eeth Koth I think would work; I'd suggest Coleman Trebor but that might be a little laughable
Bounty Hunters: lots of those (well 5 anyway) but artistic interpretation could work out for them. I'd like to see 4-LOM and Zuckuss
Lots I don't think would work either:
Jabba - not really much of a fit --> drooling harder than usual?
Jawa - cool concept, but a bit of a stretch to me
Ewoks - oh puhlease, stoopid little fuzzballs, maybe they could make them out of real fur so you can hug them too
Nah, I don't think about this line much.
