Well, technically Aizen is immortal if I recall well. So if he was to absorb powers from Yhwach, then Yhwach was to loose it forever, right? I mean, he can only regain it when the person who took it from him dies. That also made me think that it could be one of the possible ways of destroying Yhwach, but I doubt that would happen.
