I like the execution of Ben surviving in this version, but what would happen next?
Different editor here, but the two options could be
-End the movie almost as soon as the kiss happens
-Edit it so kylo is on Tatoonie with Rey as she buries the lightsabers, using footage of him from the desert earlier.
I chose the former for my try-out edits

That worked surprisingly well, you could save the scenes with Ben and Rey till after the celebration, making it the final scene.
