Has anyone experimented with replacing the dated digital model of Maul’s top half falling down the shaft? A CGI replacement probably wouldn’t look more realistic, but if it was smaller like we were seeing it further down, its fakeness might be less obvious. People are doing some wild stuff with Battlefront assets these days…
If you just want his body parts to become smaller while they fall, you could try to rotoscope them out, use a digital zoom on them and put it on a clean background. That should be rather easy to do. You could use runwayml to mask out maul and use a still image for the background. (if it isn’t already a still frame in the shot where he is falling, I can’t remember that right now)
