Hello Paul!
I find Your problem quite interesting but I don't have a real solution for
You. Recently I found this very informative page on cartography:
http://www.progonos.com/furuti/MapProj/Dither/TOC/cartTOC.html
Projections:
http://mathworld.wolfram.com/topics/MapProjections.html
http://en.wikipedia.org/wiki/Wikipedia:Featured_picture_candidates/Projections
Maps and day/night:

Perhaps that can help You a bit. Let me know if You succed. There are quite a
few programs out there that can reproject maps. I'm lacking the time at the
moment for getting into this.
