Wouldn't it be the same thing as making warppoints "Wrap around the edges"?

All that would have to be done is to add WPs from far-left to far-right, and from top to bottom when generating the map, rather than recoding the whole map display.

PS: you could do this using the map editor: generate a slew of random maps, add the warppoints. To avoid unfairly knowing the layout of maps from turn 1, pick randomly from a large pool of generated maps, and/or get someone else (or many somebodies) to generate maps.
