I thinks It's unlike but has been bought up in other threads about this. The Dragonborn has no real set name though so how would they be referred to afterwards, heroes usually disappear after their job is done as well.

Bethesda stopped work on Skyrim in 2013 so no more dlc, there is a PC mod that lets you become High King but not Emperor (it would probably be a lot of work as really you would have to add at least some of Cyrodiil to the game).
