Yes, ofc. My question, tho, was whether it's technically plausible or it would mean a lot of work to do it. I still can't meassure with precision how much work do some ideas imply.
I mean, you could do this by just erasing the line of Anakin and editing the scene, or by making VFX for a shot and replacing Anakins mouth/face and keep that shot of Anakin now staring coldly at Palpatine. (the same mad man face we'll see in Mustafar later).
