Skyrim's Sheogorath is the same person as the hero of Kvatch/Bruma, since in the Shivering isles the hero became the first mortal to become a daedric prince, and the old sheogorath became the daedric prince of order (became his former self again)

True, if the Sheogorath in Skyrim is actually the Hero of Kvatch then that makes this discussion not even possible. The Dragonborn and the Hero of Kvatch are heroes, two different ones. So yeah, they are all different.
