This would give you a canon path on the first game...
Since while Aang was pretty much the same in books 1 and 3, despite his relationship with characters being different, book 2 slave route and book 4 love route don't use a canon character for you
Meaning you would be stuck in love route for book 2 and slave route for 4.
I think it would be safer to go what Korra's mom said, that she appeared in MC's body mid-masturbation. Meaning whoever was there before then - and it was not you - was just stuck at home watching porn, probably on the internet.
Probably taken as some Avatar thing by outsiders (which based on what he says can be guesses as having a "finally" somewhere), and took much less time for those in the body than for the spirit/story due to Zuko's leaving ending taking some time.
