The door is not shut on this, but here’s my current changelist for a V3. (Some of these ideas are from krlozdac’s newly published TLJ edit.)

Remove the silly mugshot of Hux after commenting on Poe’s X-wing approaching
Remove Rey interpreting Chewbacca to Luke (He just responds with “The Falcon?”)
Remove Luke’s quip about Jakku being “pretty much nowhere” (the new movies are somewhat snarky in ways the OT never was IMHO, and so I’d rather keep Luke away from that - humor, but not gags)
Remove Rose responding to Finn’s “MTFBWY” with “you too.”
Tighten up Finn and Rose’s reaction to Maz’s “Oh yes, he can” for better timing
Reinstate a trimmed version of the balcony scene overlooking kids and horses being beaten on Canto Bight
Reinstate Rey asking Kylo Ren if he has a cowl to put on
