While his friends have scoured the galaxy for Han Solo, Luke Skywalker has evaded Darth Vader’s relentless pursuit by continuing his Jedi training on the secret planet of Dagobah.

With Han finally discovered in the lair of the vile gangster Jabba the Hutt, Luke has left his training once again to join his friends in a daring rescue attempt.

Little do they know that the GALACTIC EMPIRE has secretly been constructing a new armored space station even more powerful than the first dreaded Death Star…

Which leads into the opening of the movie as we know it. It’s not perfect but it does address a few issues:

Luke’s training DID continue after ESB and his powers have justifiably improved

It better explains why the rescue team didn’t go in as a single team

It ties in nicely with ESB and ROTJ dialogue of Vader’s search for Luke

Replacing the word “begun” with “been” suggests that DS2 construction has been going on for longer, better justifying it’s advanced progress.

It allows for Luke to separate and rejoin the fleet as depicted in the original cut

Granted it begs a few questions. Why did Luke wait to ask “the big question”. Still I think it would work, as Mark Hamill’s delivery of “IS Darth Vader my father?” sounds like a question that has been asked many times before. Some of Yoda’s response may have to be trimmed to make it work, but I really think that it’s worth considering.

I like it. In fact, I may have to concede it makes more sense than my “restructuring” idea.
About “the question”, I think the script hints that Yoda has been dodging the question, which to me can be used as evidence that Luke had tried to get an answer out of him before.

Yoda: One thing remains… Vader. You must confront Vader. Then, only then, a Jedi will you be. And confront him you will.
Luke: Master Yoda…is Darth Vader my father?
Yoda: Rest I need. Yes. Rest.
Luke: Yoda, I must know.
Yoda: (reluctantly) Your father he is.
