If it’s possible, I would like to find a different shot to place immediately prior to the Hosnian system being destroyed, instead of cutting to Leia. If we can avoid cutting to Leia, it can be left slightly ambiguous about whether she is reacting via the Force to the planetary destruction only or if Han’s death is part of it. This one may need to stay as is, since it was hard enough to find enough shots to include!
THIS! I mentioned this back when you were completing V2, and I’m glad you’re still considering making this change. I understand that in the end this might be impossible, but I really think it’s worth a shot!
As far as the Rey/Finn/Rathtar scene and editing out Chewie from the Rey/Leia scene, I’d say go for it. But honestly, these changes wouldn’t make or break the edit for me. I didn’t have any (major) issues with them being there in the first place, but I guess it could be nice to have them dealt with.
