It already has been explained why they disappeared, and there already is a Dwemer alive that was able to explain their disappearance. You just need to play the older games, or at least read up on TES lore. And no, there is no reversing such a decision made by the Aedra themselves. Who says there are even any still alive from their banishment to return?
