Go for it. In the theatrical cut it made sense to have the down beat in between the Starkiller strike and the TIE fighter attack, but not here.

And yeah, it’s funny because adding that music as I did removes the bits of “Kylo Ren Arrives at the Battle” that you’re reusing. I’m sure there’s got to be a way to figure this out without having to reuse any music at all. I do like the solution of using “I Can Fly Anything,” especially as it’s the alternate from the soundtrack.
