I think this sort of thing is doable but it's probably easier for Owlcat because their games don't feature a lot of VA or cutscenes.
I think this is a big part of the problem and why I also feel that Owlcat's crpgs (and games like Pillars of Eternity) are superior to BG3 when it comes to roleplaying. The full voice over for BG3 limits the possibility to give us more story and more roleplaying opportunities because every dialogue needs a VA (who are quite expensive) and an animated cutscene (a lot which are done with mocap).
I think I've been so spoiled after playing through all of the WotR paths that I was really confused about the lack of additional content when playing the evil route in BG3.
