Seems like they've decided to commit to the mess they left of what are clearly quest threads for her in Act 3 that can't be explored at all. Deeply unfortunate.
Theoretically if there really were an Avernus DLC for her, while it would be WAY more work to account for the state of her engine if it were fixable when going into such a DLC, it would make for a lot of fun narrative variation if you could go in with a fixed engine or without one. That is EXTREMELY theoretical though, they've not sounded super interested in making additional content around our current party members.
There was an ign interview someone posted on here recently where larian devs said specifically they want to make more content for bg3 after the holidays and there are serious talks about whay that means. They even said back in September that dlc isn't off the table for bg3 which is wild for larian as a company. That combined with
withers strong hints and the note in the epilogue about a forge in avernus
I'm very confident we will see a definite fix for her. Whether that's dlc, or de is anyone's guess tho
