Yes, OP has very specific wants when it comes to casters, and that’s irrelevant to the discussion.
I suppose the question is: would players welcome further changes to core DND systems? There seems to be pushback to every change so far, though arguably ways in which Larian changes DND is more relevant then that they change it in the first place.
I for one would - as me being a unapologetic fan of PoE1&2 and Kingmaker hater probably suggests. I can’t yet talk about combat, but for certain I would welcome 2x d10 over 1x d20 for skill checks.
