I went back through your proposed changes, NeverarGreat. The vast, vast majority seem wonderful - this will definitely become my archival version. I have a couple of questions about a few of your items:

Edit out Finn’s accidental activation of the Falcon’s game table. - I was going to advocate in favour of keeping this (nothing wrong with a cheeky easter egg so long as they’re not overdone), but then realised you are including it as part of Rey’s link with Kylo, which makes a lot of sense. So is the main reason you’re taking it out here just so you don’t repeat a shot? Or for the benefit of not putting a joke in that earlier scene for its tone? Or for using its lightness to contrast with the threat of Kylo overshadowing it in the interrogation? I don’t have an opinion either way, I’m just interested to know the thought process.
Re-score the in-universe music in Maz’s castle to something more in keeping with the Byzantine decoration. - This is the only one I have a strong objection to! I really love this song. Which is subjective, and perhaps you don’t, but I don’t feel like the song not matching the decor (in a fictional universe only borrowing from our own) is strong enough to justify the change, especially weighed against the quality of the song.
Kylo’s conversation with Snoke is bereft of Hux’s intrusion. Snoke does not learn the location of the Resistance Base in this film. - Sounds perfectly reasonable since this is using Hal’s edit as a foundation. Do you expect to need to do anything to TLJ (which AFAIK you don’t have plans to touch yet) in order to accommodate this? TESB didn’t need to explain ‘oh btw they’ve been found’, but again I’m just interested to know what if anything your plans are here.
Remove the final journey to Luke’s island. This material is instead repurposed as the dream sequence preceding the interrogation. The final shot of the film is the Falcon jumping to Hyperspace. - Perfectly good suggestion (coupled with buying the start of TLJ more time for the acquisition of bombers, etc), but again, just interested to know what knock-on effect you think this might have. Do you foresee needing to amend the opening of TLJ to get Rey in front of Luke?
Edit: You also mentioned withholding the Poe reveal on Takodana. Will you still be showing as much as possible of those lovely water-skimming shots, but just be cutting the cuts to Poe’s face?
