I'd dig seeing:
-VOTC Stormtroopers (shipped by the truckload)... Pack in a shoulder pauldron, variations (shot, dirty, clean, etc.), and I'm there.
-VOTC Chewie with collar/chains
-VOTC Leia (with a softgoods hood that works in place of the plastic hood).
-ROTS Royal Guard (Blue and Red), but include pikes (with or without the rifle, but nice if it had that too).
-ROTS 3PO... Good 3PO to see re-release with a silver leg.
-Kitbash DST (ROTJ)... DST head w/POTJ Imp Officer body.
-Clones... SA Sculpt with Utapau, 501st, Red Shocktrooper decoes, as well as a green (maybe Kashyyyk camo?) paintjob. Include the right rifle too, ditch the carbine. I'd take lots of EU variants though like the Neeyo Grunt Target figure, Night-Camo/Stealth one, etc...
-VOTC Boba Fett (ROTJ and ESB paint variants).
-VOTC Fett w/Jango Paintjob (kitbash a removable helmet/Kamino Jango head on there, and sweet!).
-Imperial Officer (all 3 headsculpts), as well as black/grey suit variants.
-POTC Figs (Pablo Jill, Yarua, Cantina Trio)
-Battledroid from the Naboo 4-pack (red and tan variants)
I'm sure I could think of others... Lots of stuff worth repacking. I agree with figures like the Cantina band Member, Muftak/Kabe, and perhaps some others too... Like I'd take a repaint of some of the Cantina Cinema Scene figures too.
Hell I'd even kinda dig the Dianoga (2-piece) from the Trash Compactor sets to be released on a basic card.
It was THE reason to get those sets if you ask me (I have mine attacking Kyle Katarn).
Speaking of... I'd put Kyle and the Darktrooper out together just to see how they maybe do? I like both figures, wouldn't mind a new Kyle being made, but I'd like seeing how they did released with film figures. Test the EU waters with what you've already got that sold well the first time around.
