I wonder what might be able to be done in an edit of TRoS that makes the trilogy more cohesive without sacrificing TLJ. Most edits of the ST try to reconcile TLJ to TRoS, but that’s kind of a shame. Like TLJ or not, it’s the one that actually has an artistic idea behind it. Especially compared to TRoS.
To me, the only thing would be to change Palpatine’s introduction.
What I did was get rid of Luke’s cliffhanger in TFA and added a couple of those shots back to when we meet him in TLJ. I then replaced that sequence with Kylo travelling to Exegol (sans-Mustafar) and finding out about Palpatine (and thus revealing Snoke is an aspect of Palpatine) at the end of TFA rather than start of TRoS. This reframes but doesn’t change Kylo’s seeking independence from Snoke, just solidifies the urgency by which he tries to recruit Rey and install himself as Supreme Leader. I then put Palpatine’s Fortnite message during the battle of Crait, as the Resistance is waiting to hear back from allies just before Luke’s appearance. This helps escalate Kylo’s anger, as both mentors he sought independence from have returned to challenge him and his desired power.
I also recommend getting rid of an exchange between Max and Rey, where Max says “but there is someone that still could.” And Rey replies “Luke…” This would help take away the implication that Luke is her family. You could also remove the line and put ominous music under a reaction shot of Rey, to help imply her family is alive but evil.
I feel like the changes are conservative, keeping character arcs intact while making the trilogy more cohesive. I made more extensive changes that might not be everyone’s cup of tea, but that’s the backbone of bringing the trilogy together without disrupting what the two filmmakers were aiming for.
