Hypothetical solution untested and untried -

Going back to the image map idea for just a minute it might still be
possible to use this method to create the model you want. The method
I would use would be to paint the ocean basins white and leave the
land masses the original colors. Then use a filter index for the
image map that cooresponds to the white used in the ocean basins.
When sphericaly mapped to a globe you should now see just the land
masses with clear areas where the oceans once were.
