Did you ever play the Lone Wolf adventure books? I did, and have started to make a map of Magnamund, or at least the northern half. I will probably make a Magnamund Mod later, if I find suitable units (I don't think anyone would make units just for this). I know that both pterodactyls and Warg/Wolf Riders have been requested, these would be nice for the Darklords. Renamed to Kraan and Doom Wolves, of course 
The map will only be for ptw, and mountains really should be set to impassable for all units. The map is based on the map in the Magnamund Companion.
If you wonder what this Lone Wolf thing is, or if you want to play the adventures, check out
