I mean, yeah, but Poppasketti’s post explains exactly why just doing that isn’t enough.
You can remove her from the movie, but the scene she’s featured in doesn’t work without her. Best idea anyone’s had is redubbing her lines and maybe also recoloring her armor to make her into an entirely different stormtrooper-in-command, but both of those things are tricky and haven’t really been attempted yet.
Try doing the whole “recoloring the armor” in Adobe After Effects?
