IMO, I think if you leave out the transports landing, but go straight to the interior shot of the stormtroopers disembarking and then charging into battle, it looks good. I also think muting the Battlefront footage would help, if you were to keep it in.
Strongly agree here. Not that I’m a big fan of the Battlefront stuff, but the landing is the worst part due to the odd speed and camera angle, and there shouldn’t be any voices when they leave so that it flows a bit better into Kylo’s reveal.
I threw together a SUPER rough cut in the default Windows editor of how this would look.
