One of the DF websites has a flat map for DFx: flat_terrain.zip. You'll need to search DFBarracks, Nova-Inside, DFArena,... However, the map is almost 5mb, and it will have to be included along with your BMS file for anyone else that wants to play it.
I've tested the map, and it is pretty flat. It might have a few small bumps here and there. But over 90% is flat.
