But how does Vader betray and Murder Skywalker? With the footage that exists? Who in the cast could become Skywalker?

If Darth Maul was Vader, and Skywalker was Qui Gon? ...No.

It's always tricky, with what Lucas gave us - if we had more material, we could cut in every direction we liked ;-)

Does anyone remember the rumors that Catherine Zeta-Jones was to play a Sith Witch ?

or DiCaprio was to be cast as Anakin ...

Maybe what is "good" for the next trilogy could also be applied to our edits of the prequels:
