Possible, but I doubt it. I actually think the case is the very contrary. When Ao worked as a Hidden Mist Shinobi, in my opinion, he was actually under genjutsu not to remember that he is of Kara, similar principle to Sasori's technique that he used on Kabuto and Yura.

So basically the Ao we see now is the real deal, while the more sane and kinder version of him from Part II. was genjutsu.
