Sorry if there's a better thread for this somewhere: I couldn't find it. I have a few figure suggestions that are pretty obvious, but never mentioned.
Mace Windu with removeable arm
Mace Windu with "emperor's wrath" transparency (like they did for Vader)
Padme in her Leia hairstyle from the beginning of the film
Dooku with removeable head and hands
The Utapau landing pad aliens (equivalent to the Ugnaughts)
Walrus Man Separatist
