The easiest route is probably to have it sit with its back to a Qi charger pad, with the coils in a sort of cape over the battery. Not much added weight for the coils, and quite a neat little intro project to get it to align itself and sit correctly.
I think magnetically aligned physical pin connections are better. Charge faster, generate less heat, and better for the battery. Wireless charging is cool, but not sure why it would need to be wireless in this case.
