I like adding that theme to the scene, I feel like it should come in a little later, as Rey starts to notice that Kylo has no intention of saving the fleet. That way it can build faster and not feel repetitive. But I like that idea a lot.
Darthrush actually did something like that, when he tried to rescore the scene in his edit of TLJ:
It also moves the big climax of the song to Holdo’s lightspeed kamikaze, which helps it fit much better.
Amazing. I had thought of an arrangement almost exactly like that one, and it worked pretty well. Now I’m convinced to keep the full track, it fits so well with Holdo making preparations for her manouver.
I also prefer having the music swell when Kylo offers his hand.
