And now to think of it…you can really use those shots of Luke contacting Leia to make him do anything across the universe with the force in this movie. The sequence works perfectly for that purpose. The question is where it can be best used and I gotta say, this is a great option.
Luke throwing the ship through hyperspace at Snoke’s ship? That would remove Haldo, which would be a plus for me.
And in your edit that could be Luke’s final act of heroism!
That’s brilliant.
Just find a great musical piece to set it over and your good.
And you could even switch it up so that you use the Luke contacting Leia scene for his Crait projection, have Luke live, then you show him hovering above the rock when he is moving the Raddus, and THEN he stares at the binary sunset to end the film.
