I can go on and on. ulfric would be a better candiate for the talos thing than our player.
There is a theory that the... entity now known as the god Talos is not simply one individual who ascended to godhood, but a conflation of three different individuals who became so inextricably linked in fact, fiction, myth, and legend that it's no longer possible to tell who was who and which one did what. And that those three different individuals were playing out their own version of an "eternal triumvirate" consisting of the archetypal figures of General, Rebel, and Observer (I think those are the right three).
So there's also a theory that in 4E 201, when Tamriel is again in the throes of a major crisis and the future of Man and the Empire(s) of Man is in doubt, we are seeing the return of this trio in the persons of Tullius, Ulfric, and the Dovahkiin. And that in the distant future of TES, the lore will not be clear on who was who, and who did what, only that there was a great crisis and that a figure emerged to save the day. Or something like that.
