That works perfect for me... how about a running change on Mjr Derlin with new headsculpts including Coach, Norm, & Sam?
Seriously, if they put out your list, I'm not sure I'd need another ESB figure other than a accurately sculpted & painted probot and army builders, such as Jesse Jame's suggestions:
Super Articulated Hoth Footsoldier... This is a must considering all previous attempts. head variants, removable hat, working holster w/sidearm, and rifle. Head variants would be nice (bearded, clean shaven, and a black dude).
Super Articulated Imperial "Snow" Stormtrooper... If the Rebs are sporting a SA trooper so should the Empire. Cloth face-mask, cloth skirt, working holster with blaster rifle. Just a nice vanilla Snowtrooper with tons of articulation.
Hoth Technician... Good articulation, removable techs cap (with the ear flaps), tools, etc. Articulation like VOTC Leia or something could work.
Imperial Commander... Generic, super or VOTC Leia style articulated figure with removable officer's kepi hat (with head variants). Black uniform variant and grey uniform variant. One head has to be Jeremy Bulloch as the Officer in ESB.
