Okay, I found some time this morning to play a little, and was able to replace one of the stormtroopers in the wide running shot with phasma. In fact, it’s the stormtrooper that Finn jumps over as they run towards the shuttle. The only question would be how to get her into the previous shot. I think the trooper immediately over Finn’s shoulder would be too difficult with all of the rotoscoping that would need to be done. It also doesn’t appear perspective-wise to line up with the trooper than Finn jumps over. This is first pass, so curious if this plus a more obvious reveal in the first shot would work!
