I bet Aizen is just waiting for his sentence to expire. He's immortal, and in 20k years everyone who knows him now will be dead. The Shinigami alive by then will know him only as this ancient killer whose sentence is finally up. He can then trick them with whatever new scheme he's got, and Ichigo & Kisuke won't be around to stop him.
