That could be good as well. And even then, perhaps not that difficult. Just show a guy in a dark robe doing the fighting, and aalenfae wouldn't have to find a Hayden lookalike. I just always pictured most of the murders done while Vader was armored.

Of course, the difficulty with this scenario is how aalenfae would work it into the existing plot. Might be difficult to alter the explanations for things. But maybe not. I dunno. I really like the idea of keeping Padme alive on Alderaan, but how to split the kids if she's still alive and Vader is undefeated and the Jedi still live...?
