I can verify this works with minimal issues. No more issues so far then playing with regulars. Would be a huge mistake if Larian doesn't make this available. I have enjoyed the game much more playing with 4 custom peeps. Honestly I could never go back to the regulars NPC's.
It works for me too, can confirm. A custom aprty of 4 is a blast. The lack of custom dialog in the cutscenes even when they "talk" is a bit off though.
