I want Sue to have a single ability/change in body that the others have. Sue can bend light around herself making herself invisible to anyone's eyes. In a way, that's kind of like a force field stopping light from actually touching her body. That makes sense to me in that she doesn't have two unrelated powers, but instead two resulting abilities connected with her rocket ride souvenir. If we think of the invisibilty as stopping light or radiation along the electro-magnetic spoectrum and her force field as stopping matter, the two, to me anyway, seem connected enough.
