Could you possibly add this to AWIP. It could be set up so that after you are done with the area Payne says "Quite an adventure old chap, thanks for the company, but I must be off now." He then walks off and you don't see him till later in the game. I suppose you would have to put something in place so you couldn't actually go there with Payne in your party if you haven't saved him in the first place. Plus you would be able to bring back a throwing apprentice as a follower. I'm sure lots of people would appreciate that.
