Nah, just go to the foothills nearby the marefolk village to get the cursed armor to brint
When you give the armor to brint just wait, let him get cursed and you get a new amazon cowgirl companion
No you cannot get her anymore, once you enter the outskirts that locks the armour away permently, when you go back to the shrine it will have collapsed.
Disappointing as I easily have 50 hours on this save. Guess that will be for a 3rd play-through in a few years.
The logic behind this is that the writing accounts for either Brint being the same or Brint becoming Brienne by the time you meet his family, but trying to account for 'Brint could become Brienne at any point in their associated content' would basically require writing a ridiculous number of variations to account for. Hence the game enforces that you either get Brienne before entering the KM Outskirts or you've cut off that thread forever.
Mind you, the game gives you fifty save slots built-in and as many of your own as you care to make. IF you don't want to get caught up like this in the future, consider making a few backup saves at various points so you can unwind progress. I'd also suggest checking your auto-saves but if you've played for any significant length of time past first entering KM (ie, ten hours), odds are that all your auto-saves are too new for one to still exist that's before that point.

Of which I only recently learned like last month lol, and yeah its a feature to save Wsans fucking sanity of trying to write around something like Brint changing after meeting his family.
Also how would you explain to his future harem that we turned their master into a girl. Even Wsan has limits, so it is understandable that he would put a time limit to getting Brienne. Wish that the game would have told you so, but eh.
Holy cow.
Thanks for that highly important bit of information. On my latest playthroughs I was aiming to use Winter Knight Brint in Undermountain and then switch to Brienne afterwards... thankfully I only ruined one save file.
