Wow, what a ton of stuff has happened in this thread during the daytime! First off, do not worry about breaking ground on V4. This is worthwhile stuff that merits it!

Let me interject my thoughts on the big pieces of the day.

Luke. I don’t imagine adding Luke’s voice in other sequences than Ach-To feeling right, and that clip of him speaking to Ben about healing Rey sounded to me like Luke was sternly saying, “Ben, kill yourself.” But, it’s exciting to have a quality Luke AI voice to use. I wanna target its use to just things that were already existing problems or goals. For the conversation with Rey next to the burning TIE fighter on Ach-To, I’d be happy with simply having the phrase “final lesson.” To me, interjecting something about Leia for Rey to react to with “wow, she still trained me though” feels weird. Makes it seem very elementary of a problem, like Rey is shocked that Leia was aware that she was having a hard time with self-confidence. The ‘Rey Nobody’ version may simply need this to be the case, but for the main ‘Rey Palpatine’ version I think it’d probably be better to omit that bit. For the Leia training flashback, Leia’s face displays some emotion so I don’t think it would fit to just say she decided to go with her political career; there should be something there but I’m not sure what.
