I think you are moving the goal posts and grasping at straws. 231 country labels in the equatorial plane with no correlation to longitude? Why bother?
The white group (below) uses longitude only (latitude 0) to lay out country labels but as you can see, they overlap (as expected).

I hope you’re here to learn and not just get people to do your work for you? I’m beginning to wonder.
P.S. Maybe I answered the wrong question? I already said this a few posts back:
If you can internalize the ‘Curves’ and ‘Regions’ output of Import SHP we might give it a go but I can’t help thinking that a spherical mapping of land masses and countries (as curves) must be available?
