True, and it would also bring some more weight to Anakin's feelings that he shouldn't have killed Dooku. I mean, if he was a Sith there's really not much way around it-- Sith = bad, and Jedi need to fight them. If Dooku is a rogue Jedi though, then it does bring more weight to Anakin's decision to kill him-- like, was Dooku really wrong for joining the seperatists, or was he simply following his Jedi beliefs in a way the others disagreed with? Since he had a red lightsaber in the movies it pretty much removed any moral ambiguity from his character, but giving him a blue or green saber would restore it.
