There are actually edits that do what you suggest about leaving Anakin/Vader ambiguous or leaving Padme alive.

For me, this is just what I wanted to do for my edit. I wanted to make something that fits better within the new canon post-Disney, and Padme remained really dead in the new comics, and Leia is Bail’s adoptive daughter throughout Rebels and Rogue One. This edit is just a reinterpretation of the same in-canon events, I’m not trying to “fix” anything in canon aside from characterization and arguably the filmmaking in which it’s presented.

It’s still a decently radical edit, but I’m not changing what happened in broad strokes.
