I feel like we've gotten of track. So this is how I see it. Alduin is a dragon and only a dragonborn can kill him. Mehrunes Dagon is a daedric prince and he can not be killed (as far as we know) he can only be banished by one of the 9 divines. Since Alduin is not one of the 9 divines he cannot banish Dagon. And Since Dagon isn't dragonborn he cannot kill Alduin. I'd say this is a draw. They would just be fighting for eternity.
