Well if they are going to do any 12" EU, why not:
Grand Admiral Thrawn
Kir Kanos Royal Guard (done like Ultimate Jango!)
Yuuzhan Vong Warrior
maybe Aayla Secura (who's actually in a movie, I know, but who started as EU - and OK, I just want her figure, alright?!)
If they sculpt a 12" Twi'Lek gal, how easy it would be to do an Oola by Jabba's side with a little bit of facial feature tweaking, once they had an Aayla Secura (or vice-versa).
