I would try. I imagine it might be even better than pineapple since orange doesn't have the tanginess that pineapple has, so gives a more clean sweetness.
The cheese could be for the invisible woman if we add pineapple to the other remaining slices, since it's a stretch for some people to even consider pineapple as a topping. Note: I am not advocating one way or the other as pineapple being a viable topping on pizza. I stay out of those fights.
