New Game Mode Idea

I think a new mode called clash of superpowers would be cool. It would be the historic world war map with all territory occupied by 5-10 playable superpowers, starting with a vast territory and significant army. For example, the US could control both American continents, Britain could get Ireland and Africa, USSR would get Eastern Europe, China would get the rest of Asia, Japan the Pacific, and either France or Germany would get Western Europe. It would also be cool if all the powers were balanced but had different strengths like Britain and US having strong navies, China has strong army, etc. This is all just brainstorming and would probably need changes to be applicable and balanced, but reply if anyone has suggestions or thinks it would be cool, thanks.
