His own complete hypnosis surely can't affect him. To activate any given illusion, he needs to unsheathe and activate Kyouka Suigetsu, which means that he is touching it prior to the illusion coming into effect. Ergo, he can't be affected by it, because touching it prior to Kanzen Saimin is the only sure way to escape it. Even if it were possible for him to willingly place himself under an illusion, he would have no reason to do so. Placing an illusion on himself which made him think he had unrivaled power would be of no benefit to him, as he would only possess his real strength and if he falsely believed he had more then he's become arrogant (as he did in his evolved forms) and take less precautions. All in all, it would be senseless of him to place an illusion on himself, and is therefore something Aizen would not do. Kyouka Suigetsu cannot exert its own will over Aizen either. The Hogyoku can't be an illusion as Urahara, who wasn't influenced by Kanzen Saimin, tried to make his own. And again, the Hogyoku being an illusion would serve neither Aizen or Kyouka Suigetsu any beneficial purpose. Aizen can swap places with Hinamori easily, remember Kanzen Saimin controls all senses, so he could easily switch places with her at any point and his enemies would still be convinced of what he wanted them to believe. The difficulty, as an audience, in knowing when or how Aizen switched, is because we don't know when what we're seeing is reality or when we're seeing it through the manipulated eyes of the characters.
