It's a good theory, and I can't really say it can be absolutely disproved. Still, I agree with Purrington. Even with the proven instances where Daedric Lords are able to enter Tamriel (Sheogorath posing as Sam) it seems unlikely that Sheogorath has taken such an action himself. The closest (certain) time he's ever done so was to create an island to find a champion to fight for him, though all the real action of that event was in Oblivion and specifically in the Shimmering Isles, a realm in Oblivion rather than Tamriel. In Skyrim though, his only appearance is inside the mind of a dead man, immediately after which he agrees to return to the shimmering isles with his follower. I suppose theoretically he could return as Cicero (or have been Cicero if the DB missions were done before the mission) but it seems too unlikely.
