What about:
6.4.2.8 Spherical projection
Using this projection the scene is projected onto a sphere....

Rendering the scene/image you would like to add to the sphere with a
spherical camera, and then mapping it onto the sphere with spherical
mapping, the image won't be fish-eye disorted.
Just a thought.. Or did I misunderstand the problem?
