Serpent's Trench Map

Is there Anyway to have the Serpent's Trench Map as a fully playable map like the WoB or the WoR? In the Hack I'm currently working on, the game I'm basing it off of (I won't tell you what game until I actually have some Visuals done for it), has a third overworld-like map. I mean I can probably just use a regular map to do it, but I want to see if I can do it with Serpent's Trench map first.
