You could design a map like this and submit it if you wanted to! Just go to
https://www.cubecraft.net/forums/map-submissions.52/ and submit your map, making sure to have screenshots and Information about the map. Good luck if you make a map!
If you don't want to make a map and are suggesting that someone else should make one, I would suggest to include more info about how you want it to be designed. E.g. How many teams, how many total players, how many players per team, how many generators at each given area, and the layout (Are there sub mids? Are there pre built bridges, etc.)
