YES. I had a very similar idea.

The PT prologue is my next project, and I was probably going to mostly save the reveal…until the last second of the film. It would end on Vader’s breathing. In my mind, this film would be built to be viewed in Machete order (after Empire).

I’m working on a ST epilogue edit now. Most ideas I had are very similar to yours. However, it focuses on both Kylo and Rey, starting with the Kylo/Vader scene. These characters both represent the legacy of the OT. My edit will still include a couple of scenes from ROS, mainly some training, Death Star fight, and the final scene of her on the desert planet, though higly edited; this is mostly because Rey/Kylo are the central characters of this story, and I think we should see a solid conclusion to their arcs. You’re welcome to check out my outline for the project if you wanna take a look/provide any feedback/maybe partner up in some respect. Excited to see what you do with this!
