If Aizen comes back as a villain, he will be much more balanced. He is without a Zanpakuto, no Hogyoku either. He will have to rely on natural strength. It is heavily implied that he is coming back and I think Kubo saw what he did wrong with the character. He is going to take him back a step while bringing the others up. You saw in this chapter that Aizen is the measure they are using for strength now. If he comes back, others will be on his level.
