Well you could do that yourself, can't you? There's even two ways now - either as a structure generator, or as a plugin. Both should have sufficient resources available to do the job.
But first you'd need to do a bit of a research - how common are the dungeons? How many per chunk should the generator make? Is there a height distribution function / limit?
