If it is possible.
then cut “henceworth you should be known as darth vader” — therefore cut palpatine rescues anaking on
mustafar, keeps the mystery of vader intact, audience would assume anakin died on mustafar or at least leaves a
questionsmark. Also i think the surprise in rebels with ashoka and vader would be more powerful. Up to discussion is

Whenever this is done in any PT edit it completely ruins the film. There is not a single life form on this planet of nearly 7 billion people who does not know Vader is Anakin. Not one.

The story of RotS is the fall of Anakin Skywalker. If he doesn’t become Vader at the end then he is not fallen enough. The emotional weight in ESB is Luke finding out who his father is, not the audience. And the tragedy of RotS is watching the hero of the Clone Wars fall as low as he does, not to trick the audience into pretending not to know something they already know.

Same with the Rebels connection. It’s Ahsoka who’s shocked by Vader, not the audience, and it would be impossible to manufacture any scenario whereby you could take the emotional weight out of RotS successfully just to serve as a punchline for a little watched show and a decades old film.

Same with Padmé naming her children. There’s also nobody on the planet who doesn’t already know Luke and Leia are twins, all you’re doing by removing that is removing the flow of the story to pretend to preserve a long dead idea of suspense.

It’s manufactured and pointless and worse, breaks up the flow of RotS.

1:55:28 – cut empire scene with vader, palpatine and death star, therefore we got Rogue One
so 1:55:28 end of the movie.>

Maybe mask out the Death Star, but even if it’s not, there’s no need to change this scene. There’s decades of experimentations that need to be done to the Genosion weapon before it reaches the stage seen in Rogue One.
