Hi there!
I feel like this thread is probably not quite in the right place, this is more for features which can be added to the game including tweaks to how the game is played and the UI. The maps are made by members of the community, so it would be better asking them.
Though I don't know exactly, I feel this thread would be better suited to the "Beatmap Projects" forum (
53 ) where I have seen others asking for requests ~ try there and you might get more luck!
