Despite myself being at peace with the Luke Vs Kylo fight it would be really awesome if someone reimagined the fight & use 3d doubles to give us an actual saber fight!I know that would require alot of work but can happen right?
This is very very hypothetic but if someone would bother to add a fight I think actor doubles (with digital faces if needed) would be the easiest way (but far from easy) to pull it off convincingly. Of course it can happen, but I doubt it.
Also I’m not sure the projected light saber could clash with a real light saber.
