Interesting concept. Though as Captain said there is no precedent for this concept. If normally you have a cycle or death and rebirth and the only thing that step out of that cycle are Hollows. When a Shinigami "kills" a Hollow they are brought back into the cycle. When a Quincy kills a Hollow they disrupt the balance by making sure they never are returned to the cycle. The biggest issues are does the same issue work for the Arrancar. As far as Shinigami in your concept there would have to be some detail allowing a Shinigami to go to Hell. Currently Hell is for humans that have done evil in life and degenerated into Hollows. So they are already qualified by their lives in the human world, that continues on after death as the degenerate into Hollows and then killed in that evolution are sent t hell. The question would be is, Are there anything the makes what one does as a Shinigami determine they dont belong in the cycle? Most Shinigami aren't born so they have done good in life in order not to die and degenerate into Hollows in great numbers.

Its a interesting concept thought I don't think Kubo would necessarily do that besides even if there was a being that was Aizen he wouldn't be Aizen as we currently know him. He would physically and mentally have to change to have some concept of freshness for the new storylines.
