The idea that all of them could be the same is flawed severely, with one major hole. The player character in Oblivion was recognized by the Emperor at the start from his dreams/visions, as in, he has no previous personal connection to the hero, meaning they could not be the Arena, Daggerfall, or Morrowind hero, because all of them worked for the Emperor. The Arena, Daggerfall, and Morrowind heroes might be able to be the same, I don't entirely remember if there was anything to contradict that possibility.
