Create a null (3d). Make all your logo layers 3d. Link all to Null. Move all in z space forward. Offset by rotating on Y axis. Rotate null on Y axis = logos rotate in 3d space. It's now a matter to figure if the z offset of the logos from the center Null is enough to make the logos rotate on an orbit that is bigger than the sphere.
