Yeah this is supposed to be an angrier, unrefined Vader, and Kylo’s entire shtick is being a Vader wannabe. Any similarities aren’t a big deal imo (I didn’t notice any though).

As for Obi-Wan and Vader’s last goodbye conversation - I’m not sure that requires any tweaking at all in terms of dialogue. It’s pretty close to solid, and Ewan & Hayden deliver some great lines. It’s already self-evident why Obi-Wan can’t follow through with killing Vader even after what seeing he’s become. It’d be too on the nose to include a flashback of Anakin to try to justify it.

EDIT: I was looking at the main post and the “Alternate Vader Sensing Kenobi” fix. Is there a chance this could be enhanced further? We have enough footage for it. I feel if I showed this scene to someone who’s never seen the show, they’d be confused why a bald man appeared in the middle of Leia’s fall.

But I like the concept of Vader detecting Obi-Wan across the galaxy. It’d be interesting to see whether the scene order can be tweaked.

Leia rescued and says “You really are a jedi” and they leave (cut Obi-Wan’s reply line to linger on Leia’s last line)
THEN reuse Mustafar castle establishing shot, background audio of bacta tank breather that sounds almost like Vader breathing
Reveal Anakin waking up, maybe background audio echo of Leia saying “a Jedi”
