I want to do so much more... 
I've been trying to figure out how to fit overhangs / cliffs into the scheme I'm proposing. Because I LOVE overhangs And I think it's still possible - I'd put it into the "terrain composition" category. In certain biomes, after it receives the terrain height, it can actually add up to the value, creating the slopes up and the overhangs under them, eventually. So despite the terrain height generator generating a normal terrain, it will eventually contain overhangs above the height initially generated.
I'm not sure, though, if other structures, such as villages, can be made to work with this.
