It would make sense for him not to use it since it would probably have serious repercussions. The only thing Aizen can't hypnotize with his shikai is time. If he was able to control time with his bankai, essentially, he could screw with his opponents. However, I don't think he could hypnotize time, rather change it. Like he could backtrack a couple of years and come back to the current time and the opponent would feel all the pain they felt from the period aizen went back to. Just my opinion.

It's too far away from his Shikai ability. Shikai and Bankai always do basically the same thing - the Bankai is just a greater, grander, more powerful version of the Shikai. Hypnosis and temporal manipulation are just too distinct as concepts for one zanpaktou to have both.
