No being with divine spark can be killed as far as we know. Even Lorkhan is still kind of around. There's also one major flaw in this theory. The Dark Brotherhood are wrong. Sithis isn't a being, he's more like physics. They're really chatting with Mephala, or possibly Vivec, but most likely Mephala.

There's also the recent interview with Haskill that basically says that he was the mortal of the Grey March at the end of the 1st Era just like the CoC, just like Arden Sul of the 2nd Era. The CoC was never meant to mantle Sheogorath and the guy we talking to in Skyrim is regular old Sheogorath.
