I like the cinema scenes that came out from POTF2 and TPM.  Why not continue that?  Start with ROTS.  And have them all be SA.

Utapau Hangar Duel (Obi-Wan, General Grievous, Grievous' Bodyguard)

Mustafar Final Duel (Obi-Wan-scorched outfit, Anakin-scorched outfit, Mustafar burly)

Chancellor's Showdown (Mace Windu, Chancellor Palpatine, Anakin)

Slaughter of the Jedi **Mygeeto** (Ki-Adi-Mundi, Cmdr. Bacara, Marine Clone Trooper)

Slaughter of the Jedi **Felucia** (Aayla Secura, Cmdr. Bly, Clone Trooper)

That's for starters...
