I don't disagree with you at all. I completely understand your rant. However, I just find it a worthy endeavor to try to make the trilogies interchangeable. Honestly, I'd enjoy watching the films pretending that I'd never seen the OT, and being surprised. But I won't argue with you. Your solution is simple and effective. Not a bad thought.

In order to address part of your concerns (assuming we know Anakin is Luke's daddy, but not sure that he's Vader), what do you think of flashbacks? Many people aren't interested, as it isn't Star Warsy in nature. Perhaps there'd be a way to include it in ROTJ without being too distracting. Likely during Ben's chat with Luke, some flashbacks could be squeezed in there to show Anakin with his final limb pulling himself up the ashen hill. Maybe just before Luke removes Vader's mask, we see a flashback of Vader getting "put together" and his mask placed on his face...just thoughts. What do you think?
