Yes, but it would be an effort that does not come down to any strength, machinery, physics or logic, because in his universe the Narrative Force is infintitely stronger than any natural laws.

And the hammer is ruled by a strong narrative: Thor’s storyline.

So he would have to create a compellig narrative where he moves the hammer in a way that makes an interesting Thor story.

He can’t just move it with a planet-size magnet powered by the sun itself, but he could move it with a planet-size magnet powered by the sun itself if it could be explained in a cool way and gives Thor a great struggle to overcome, causes tension to test his relationship to Odin, or moves his character arc.
