I have seen a similar idea "Map object enhancement". However that idea requires development effort.
My idea would be to create a repository of colored maps, where the world, countries and regions or provinces could be found in perfect working order and ready to be used in board.
This repository could be stored either on Boardville, thru board itself or any other means and be increased slowly by the community.
Most people tend to typically require countries and regions, and having such a repository would decrease time to implement maps, since the biggest effort there is sometimes to just find the right maps.
