It would also get rid of cutting to Leia in hyperspace for one shot only, and then immediately back to Rey and Luke, and there seems to be no clear consensus on how to approach this transition.
Because that wasn’t the transition when the scene was still in the movie - it didn’t cut to Leia for one shot, then back. It cut to Leia and then followed the Resistance plot for a bit (with the Finn/Poe jacket scene, then the demotion scene).
Johnson said the Luke scene was a casualty of restructuring that portion of the film in post production - originally there was a lot more cutting back and forth between Ahch-To and the Resistance plotlines, but eventually they decided to stick with each plot for longer stretches of time.
Another example of this is the prison escape and fathier chase - the moment when it pans down to the manhole they escaped from in prison directly to the manhole they emerge from in the fathier stable? Johnson said in the commentary that that was an edit point where they would have transitioned back to Luke and Rey with an optical wipe.
Including a lot of the deleted scenes will require more restructuring than people seem to realize, I think, as several of them seem to have been casualties of reorganizing the footage in editing and won’t fit back into place without some more reshuffling.
I do like your idea of moving the Luke’s Moment scene though, that’s something I might have to play with myself.
