Are you serious? You're the Dragonborn for crying out laud! Go get yourself killed! This is my idea for a DLC in which you get to give the legend of the Dragonborn the ending it deserves.
After downloading this DLC you'll hear guards talking about how they willed their wills and testaments with the local steward. This gives you the task of filing your own will. Shortly after that you hear about a cursed king of death who commands an army of undead. Long story short: You form a party and go re-kill dude's army. You chase him into his lair and beat the little freak until to death.
Suddenly. Liches. Thousands of them. They keep coming until you're dead. You become a ghost.
Your comrades carry your body to your house and your family places your corpse in the parlor (living room) so all your friends can say their goodbyes. You can wander about all over the place. People and creatures wont attack you. You get to kick around and tell your loved ones that everything's OK with a little haunting here and there or just mess with random people. Then the bury your decomposing ass. From there you go to spend the rest of eternity one of three realms determined by the path you chose in Skyrim. The Void, Oblivion or Sovngard.
Wait. It aint over yet. Turns out the King of Death is now in the perfect position to raise all the dead of Skyrim. You'll have to fight all three of the realms and Skyrim. You'll have to rally the forces of the dead and living alike to strike down the King of Death in one final battle.
After the final battle you get to choose where you spend eternity or you can even come back to life.
