Hmm. This is tough.
01. Cliegg Lars (AOTC)
02. Padme Amidala (Picnic Gown; AOTC)
03. Palpatine (Office Duel; ROTS)
04. Owen Lars (ANH)
05. Tzizvivt (ANH)
06. Tonnika Sister (ANH; I don't care which one)
07. Admiral Piett (ESB)
08. Sim Aloo (ROTJ)
09. EV-9D9 (ROTJ)
10. Yak Face (ROTJ)
After those 10 (and maybe a new spirit Anakin with Sebastian Shaw likeness and spirit Yoda, both done like the 2004 OTC spirit Obi-Wan), I think I'd be happy with things ending.
