Furthermore, it would be impossible to hide the reveal... when Ben talks about Anakin being a good friend that he was tutoring, who ELSE could he be talking about? He also says that Vader helped the empire destroy the Jedi. In ep.3 we watch Anakin do all those things, and then become Vader. You'd have to ditch pretty much all of ep.3. Hmm, not a bad idea, now that I think of it.

You have indeed stated my concerns with Ady's Revisited plans. Leaving out the "Rise...NOOOOOooooooo" scene is easy enough, but it's all that other Vader-stuff that Ani does that really... well, I don't see how it's doable.
