What quantum said. You can change the map however you want, as long as you don't touch the pure white pixels (255, 255, 255) that mark the center of a province. If it goes missing, the province will disappear, and if it's moved into a different place the numbering (and thus, the terrains) of most provinces could change.


It might be easier to connect provinces in both side of the sea and draw little anchor images in the water close to them. Many maps have used that kind of a visual clue to indicate overseas province connection.
