Well, based on this

and

You might have a shot at subdividing the sphere surface into a rectangular mesh,
and using tif heightfields.

But that would be a LOT of work, and use a lot of memory and parsing/rendering
time.

Maybe just find a bump map of the moon and uv-map the sphere, using the bump-map
to create the normals.
