What if the empire won without the help of the Dragonborn, and what if Ulfric escaped before they caught him?

I would love to see a fill that has Ulfric seeking out a neutral Dragonborn(could be any gender, but preferably man or mer) and asking for their help in regaing his throne and the Dragonborn telling him that the real enemy is the Aldmeri Dominion and that the time for running in guns blazing has passed, and the best way would be to assassinate the Thalmor. Of course that goes against Ulfric's nord sensibilities and the Dragonborn convinces him to travel with them to prove it.

Bonus Points if the Dragonborn is leader of everything but mostly the Dark Brotherhood, I think it would be hilarious to see Ulfric react to that.
