I don’t think you can cut back to Kylo & co, because that shot of him is from after he gets blasted by Chewbacca (and it would get reused later when he looks up at Finn). Also cutting back to them in the middle of the firing sequence might make it feel like Chewie takes too long to shoot at Kylo.

In Starlight Chewie immediatley shoots Kylo and blows everything up before the Starkiller fires, removing all the following action where everyone starts blasting, and where Kylo looks up at Finn. I prefer it the way it is in Restructured, but I think it only works if we don’t cut back to them until after the whole shebang. Then it can be implied by the audience that everything happens soon after Han’s death despite taking a break from that scene.
