Would have been awesome, but I remember Swen talking about this ages ago and saying that it would just be too many more permutations, and I certainly understand that.
Well, if anything it is precisely the things the OP is talking about on which Swen ought to have focussed his permutations. Unfortunately, right from the very beginning, the BG3 devs have been focussed on the wrong things (for example VO, cutscenes, etc.) while neglecting the the important things.
