At least these are audio-only changes, as I’m working to get V3 finished, lol.

There’d not be a ton of room to shoehorn in new dialogue in those two shots in the opening scene, but I think I prefer, “You’re just a phantom… what could you give me?” Remember, in Ascendant, as opposed to the theatrical version everyone got the chance to complain about, we just saw a pickle jar full of Palpatine clones (or even if they aren’t obviously him, certainly clones) and heard exposition about him casting his spirit elsewhere after dying. So I do not feel a strong need to for Kylo to comment on his cloneliness.

No words would help the moment of the transfer of the saber from Rey to Ben, I wouldn’t want to add any there.

Same for Ben reviving Rey. I think the trilogy has enough instances of people saying “Rey” in isolation.

As for adding a line of dialogue after Ben dies, my only concern is that it may undercut the reveal at the end of his ghostly image.

So… none of these feel necessary to me, and would have to really strike me as working very well in order to make it in.
