Korgan + Aerie = True Mod?

Is there a mod that makes it possible to have Korgan and Aerie in the group without her quitting it after a while? I really like both of them - and even enjoy their banter but when Aerie decided to leave in the middle of the Underdark i decided to skip Korgan in the future. I already miss the little dwarf, though.

Alternatively, is there a mod that makes it possible to pick Aerie up again if she decides to leave because of Korgan? As I understand it, she's gone forever if so now.
