Here's what they could do for the final "Greatest Hits" wave, with six from the PT and six from the OT:
01. Anakin Skywalker (2005 ROTS Evolutions version with Sith Eyes)
02. Obi-Wan Kenobi (2005 ROTS Pilot with Mustafar deco and Baby Luke)
03. Clone Trooper (2003 Clone Wars SA sculpt; plain white)
04. Clone Trooper (2005 ROTS 41 sculpt in Coruscant Gray deco)
05. Darth Maul (2005 TPM Evolutions with Cloth Cloak)
06. Darth Sidious (1999 Episode I Holographic version)
07. Stormtrooper (2004 VOTC)
08. Boba Fett (2004 VOTC with TESB deco)
09. Biker Scout (2006 VTSC)
10. R2-D2 (2005 R4-G9 mold with no battle damage or weird accessories)
11. Chewbacca (2005 Early Bird version with Hoth snow deco)
12. Emperor's Royal Guard (2005 ROTS version with force pike)
This way, the figures that we as collectors (okay, me) wouldn't be interested in should they be rereleased as-is, would be changed just enough and for the better to get us (me) interested. The only figures who would be straight reissues of the original figures would be the Stormtrooper, Biker Scout, AOTC Clone (all of whom would really need no deco changes) and the Holographic Sidious (which I maintain is still the best holographic figure Hasbro's ever done).
