The problem with using the Hux shot during the firing sequence is that there’s clearly a star in the sky, so it would be really hard to fake it being underground like the the other shots.
Here’s the video:

I had also grayed out Hux’s hair somewhat in the beginning of the shot to make it less obvious that it was him. However, it would probably be easier to remove that part of the shot anyway, starting it from when the camera starts to pan right.
NeverarGreat, Just throwing this out there - would REVERSING the 2 shots in this later sequence take the edge off the duplication? - so that your music would be the SAME in the background, except we’d see the female operater shot FIRST this time (‘reversed’ to turn towards her monitor in this instance), BEFORE we then see the male operator, just before the weapon fires.
I tried this reversal on the female operator shot, pulling audio of Hux saying ‘Fire’ to match the guy’s mouth movement. It works fairly well, but if you’re really paying attention the backwards footage is noticeable. I do like the ‘Fire’ dialogue change in any case.
