As amazing as the Champion of Cyrodil is meant to be, to assume that he could do something that only the man-god that started the Empire has done before him is a bit of a stretch.
Not to mention it would have to be a complete, 100% doppleganging of the Daedra, not just taking on it's appearance. Like I said, I'm not trying to take away from people that RP it that way because there is indeed wiggle-room, I'm just saying exactly what I said before: in Shivering Isles it's made quite clear that you're not Daedra, you're certainly not an immortal Daedric Prince, you're just a mortal with the power of a Daedric Prince.
Though personally I'd imagine that for the character in Oblivion to become the Sheogorath of Skyrim, that would mean that the character actually DID become a Daedric Prince.
Then there's the fact that, for all intents and purposes, Sheogorath shouldn't exist at all due to the way Shiver Isles ends. And for that matter, why isn't there a Jyggalag statue/quest in Skyrim?
-The Champion of Cyrodill is a Shezzarine, an avatar of Lorkhan, exactly as Tiber was, exactly like all the heroes of the games are. He was bound by fate and destiny to be super powerful.
-Not really, the process of mantling can change the appearance of someone and give them god-like powers without actually 100% doppleganging them. Talos is just Lorkhan/Sithis/Shor reborn yet people dont see him or call him Lorkhan or Sithis or Shor. The CoC can look like Sheo, be immortal, and have Sheo's powers while not being a Daedra.
Furthermore mortals can become immortal through various means, mostly CHIM, which is something that all the player-characters have to some extent.
CHIM is the lore explanation for why time freezes when characters open up the inventory, and why you can suddenly come back to life by loading saves. CHIM is also the lore explanation for the construction kit and why people can modify the world yet no one in the world seems to notice the modifications.
-Also Jyggy was most likely reabsorbed into the new Sheogorath
the best explanation is here

Just as Akatosh and Lorkhan, two kings, and two rebels, have killed each other, which is to say killed themselves since Akatosh and Lorkhan are the same person, across time so to must the two kings, Sheo and Jyggy, kill each others Rebels across time.
Just as Ysmir and Tiber, two kings, and two rebels killed the other in the founding of the third empire to make Talos
and Just as two generlas and two rebels killed the other at the end of the Skyrim civil war.
It is a pattern of mythic echo stretching back to the dawn time.
