I am at least 101% positive that Aizen just wanted to kill the Soul King and rule over creation in his place like Yhwach did. He didn't care one bit about the Quincies, the only one that could put up a fight against him was Yhwach (who was asleep at that time) and Aizen only ever really cared about himself at the end of the day.
