I think that a command called '/generatestructure <structure> should be added into the game. When it is typed and <structure> is replaced with the name of a type of structure (e.g. village, stronghold), the specified structure should generate centred on you. I do think that it should only work in creative mode though. It would be quite interesting to find out what an underground desert village looks like...
