Resculpts are always high on my list of "I wish Hasbro would do it" stuff.
My list goes somethin' like this...
-
Hoth Rebel Footsoldier... Removeable helmet with multiple headsculpts. Cloth scarf piece attached on helmet. 16 points of articulation and a neutral pose. functioning holster w/RFT style blaster pistol. Blaster rifle. And for kickers a base that has a "wall" for the trench... Each base can connect to another on EITHER side forming a jagged trench sort of.
-
Imperial Cold Weather "Snow"trooper... Cloth "mask" piece on helmet. Functioning holster with scale blaster. Cloth "Skirt" piece of uniform. 16 points of articulation and neutral pose. Disappearing Blast Mark (I liked it on the CT stormie).
-
Lobot... Who doesn't want a neutral lobot!?

-
Rebel Fleet Trooper (Yavin Base)... Removeable helmet with rubbery chin strap (XD figures have them). Functioning holster with proper/accurate blaster. Scanning gun/tool. Guards Force Pike. 16 points of articulation and NEUTRAL pose. Removeable vest. Multiple head variants (with 1970's hairdos!).
-
R5-D4... Kinda like Lobot... I really want a new one with tons of repaints! Especially that orange R5 in Mos Eisley. I love the orange look.
-
Imperial Officer... Tuniced officer with black, grey, and olive color variants. Removeable hat, and multiple head variants. 10 points of articulation per figure and a chair with death star computer console base.
-
Grand Moff Tarkin... Grossly in need of a resculpt. Sculpt him to be the creepy small man we all remember, articulation to hold his right hand to his chin, and to sit at his conferance table.
-
Lando Calrissian General Pilot... No goofy stance, just a neutral and fairly poseable figure. Give him the vintage silk cape of old for a throwback! Functioning chest holster with officer's blaster.
-
Prune Face/Dressellian Commando... First one's neat, but I'd love a second one without the eyepatch and a bit more poseable (Cloth poncho, etc...)
-
Almost every main character... I mean, look at them!

Han Endor, Luke Endor, Leia Endor, etc... I'd take great new poseable sculpts of almost anything.
