Won't gravity stop this from happening? Seriously, the shell of the sphere will be balanced on the outskirts of a gravity well right? So if it moves this will move the center of the gravity well and both the star and sphere should fall back towards the center.

According to Newtonian gravity, an object inside a sphere experiences zero net gravity from the sphere, and vice versa.
