Just watched the Lava vid that MR posted, there are quite alot of shots that could be used for sure. All the scene needs is about an extra 10 seconds to breathe.
I’m thinking of using some of them to have Kylo fly his ship to Vaders castle and have him find the wayfinder inside. It’s ambitious but I think it can be done.
If you are doing that in your cut, You could take the shot of Krennics ship landing on the platform outside Vader’s castle and change the ship to look like Kylo’s and colour grade it to fit the movie. It wouldn’t take much to change the ship because it appears very small in the scene.
