Sure, why not. I see the following things that can be made from existing (or soon to be existing) MOTUC figures:
ARMS: Royal Guard arm pieces
THIGHS: King Hiss
WEAPON: Webstor's gun in blue
Optikk like chest armour
Various other pieces (knife, gun arm bracelet, etc.)
Heck, they could REALLY make it a helmet that clips onto the chest armour somehow (removeable) and include heads of MAA, He-Man and Marlena. That would be pretty sweet.
