Fate unknown after Dragonborn DLC. Likely Haermaeus Mora's Champion if he couldn't stand the temptation of the knowledge offered by the Daedric Prince from the looks of things.

As for other Daedric Princes, whether they are canon or not, I don't know so it's uncertain. Then there's the claim that Dragonborn is actually a Dragon in human body which by the lore seems to imply Dragons are lesser extend a God. Not given a choice, answer is uncertain.

Given choice which means head canons are allowed and if you ask me, I say become a god yourself. If that shrimp Tiber Septim can cheat his way to become a God, the Dragonborn can do the same too. Hell, the LDB has all the conditions to become a 2nd Tiber Septim and unify all of Tamriel if he so choose.
