While I would love a dlc in avernus with karlach getting her finally fixed on an epic infernal adventure. I wonder how that would work for playthroughs without karlach/ dead karlach or with the netherbain enslaved.

It seems like an odd thing to try to do a post game DLC focused on karlach in a game where theres so many ending options.
(To clarify i would buy it in a heartbeat) but just seems like that would legit be MORE of a challange narrative wise to put in then a mid game dlc or engine fix prior to the end game.
