Aizen in Harry Potter verse

What if Aizen woke up as Harry Potter before Harry even received a call to school...Aizen only got his cunning,intellect and other powerful aspects of his mind while memory of Bleach verse is lost...Also reiatsu is lost aswell...

What would Aizen do from the first day of school to final battle with Voldemort?

He would probably be the next Voldemort.

If he gets the same talent and potential he had in Bleach, then he most certainly would become the next Voldemort. . .and he would probably succeed.
