Not exactly sure what you mean, but I'll try and answer.
If you own a copy of Halo PC you can download the Gearbox patches (Halo: Custom Edition, and the Halo Editing Kit tools [you'll need 3D Studio Max to make a map though, and no there is no other way around it])
But, if you don't want to go the troubles of actually designing your own map by hand, you could simply post here, and hope someone makes it, or uses your idea.
