I feel like moving mustafar and palpatine to later in there not only works, but you don’t have to do AS much work to the sequence now, either. You can probably pull the stop on the Star Destroyer and the TIES coming down from it to the planet surface. And so far as “buildup” goes, I feel like putting that sequence about 15 minutes into the movie serves that concept better than trying to stretch one minute into two.

Rey’s still referencing the lightspeed skipping that’s been cut, though (I think that sequence might as well stay in, myself)
