I don't think that Trump is going to take back the Presidency at this point. It would be really bad optics, and he knows it. Even with all the evidence indicating that the election was stolen, it just wouldn't be a good look for him. You'd have a whole bunch of people, even some who might have supported him otherwise, calling him a dictator.
Besides, I don't think it's Constitutionally permissible at this stage in the game.
