BBBG, that won't work, Warlight, doesn't support groups named as territories or bonuses.
And on the map: I can hardly tell the differences between 1.1, 1.2 and 1.3, but 1.4 looks like a whole new map to me! If I were you, I would just graphically improve 1.3 (especially Greenland!), and start 1.4 as a brand new map family. It may be of the same region, but it's at a completely different scale.
And if you're making a map of the map of the western hemisphere, you need to include parts of Europe and Africa too. Wouldn't 'America' suit the map better?
