To me there are 4 distinct Box Sets I'd Like to see:
Jabba the Hutt w/ Bib Fortuna, Salacious B Crumb and Squidface
Hoth Luke w/ Tauntaun and Wampa and Hoth Leia
Droid Sale Set: Jawa, Uncle Owen, Aunt Beru, R1-G4 and Power Droid
Jabba Skiff Guards: Barada, Klaatu, Klaatu, Nikto and Weequay
I know there are several people around here that would like something along the lines of:
Endor Rebel Soldier
Hoth Rebel Soldier
AT-ST Driver
Generic X-Wing Pilot
Imperial Officer (Black Tunic)
I'd rather have that than repaint/retools I guess. If that's the way you want to run, most of the stuff is possible with basic bodies and new hats/scarves/paints. The bigger stuff like Jabba obviously need to be tooled.
