Yes, the main characters have been done to death, but in some cases, they're still not perfect. What figures of the main characters do you still want to see made? And don't say "I don't want main characters, they suck!" Just say which versions you still want.
*Stormtrooper Disguise - a short, but not too short, clean version with helmet, blaster, binders for Chewie, a wall console thing (like Wat Tambor) from the cherry red control room, and lots of articulation.
*Yavin Ceremony - both of the ones we have now aren't very good. Do it in a scene with Han and Leia (details later). Give him a medal, and make him sort of smiling, but not too much. And a blaster in his holster.
*Rebel Pilot - based on ESB/ROTJ, from the Hoth and Daghobah scenes. Maybe with removable coat and chestpiece/hoses, for when he's talking to 2-1B. At least with a helmet (with adjustable visor), switchable hands (regular, shot, and gloved), and articulation.
*Endor/Death Star II - like the Jabba's Palace one. Heck, even use his head. But a new right hand, with a glove, and so he can hold things with it. And a DSII body, with more articulation than the Saga Jabba's Palace version. With lightsaber, binders, helmet, cloth poncho, belt, and a crapload of articulation.
*Stormtrooper Disguise - a correct height, clean version. With helmet, blaster, rifle, console ("Boring conversation anyway!"), and articulation.
*Yavin Ceremony - in the aforementioned Screen Scene. With his collar tucked in all nice and neat, maybe smiling a little bit. And a medal, plus a blaster in his holster.
*Echo Base - without his hood on, or his head wrap thing from the POTF figure (which he didn't even wear). From when he's talking to the deck officer. Includes blaster.
*Bespin Torture - everyone wants this one! He should be getting ready for it, just try to make his face look right. Includes light-up torture rack with sounds and moving chair thing.
*In Carbonite - the other block is too wide, and not very accurate. Have one that can actually be enclosed in it, maybe have a removable front part a la ROTJ? However he should be clean, and with the right shirt (without buttons, preferably). His arms can come off and switch places with Endor Han's (see below), and his hands too so for different poses. Includes carbonite block, wrist binders, arm binders, and articulation enough to make his arms in the position they're in in the carbonite.
*Endor Trenchcoat - the other one is too bulky, and the accessory pack version isn't right. Make it plastic again, but make the figure look good. And have his arms be able to switch places with the carbonite version, so we can take his coat off, like Dodonna and Antilles, plus his hands, so they're not open like he's in carbonite. With blaster and Endor base, maybe with snapping twig.
Princess Leia Organa
*Yavin Ceremony - in the Screen Scene. The correct height, with no medals but able to hold them.
*Jabba's Slave - laying on her side, like she did in the palace. She doesn't really have to be able to stand up. With metal chain, pillows, and sitting, horny Salacious Crumb.
*Endor Gear - sort of like Luke. Without the giant crotch from the other versions, please. With helmet, cloth poncho, blaster.
*Ewok Trap - the VOTC one looks great, maybe with less articulation so it can be less money, though. Includes dead animal and net, with clasp so R2 can "cut" it in half.
I'll do more later.
