Accepting map submissions.

Sometimes I go with friends to their place and we like to play Heroes of Might and Magic V, but playing the same map is getting a bit boring (even on Heroic difficulty, the opponents aren't very strong – we already remember each of their moves and know for sure whether they will attack or not). So here’s my request: Please make a map in the shape of a "cross" (on land, this would be 4 islands of equal size, and one in the center with an entrance to the Dungeon. In the Dungeon, it should be the opposite: One large cross-shaped continent with sea in all four corners. I think this will be difficult because I have already tried to create it in the map editor. After all the struggles, it told me that it won't open it anymore). It should be for 4v4 battles. I would be very grateful.
