sorry, pal, but its just not realistic. i mean, sure, osteopathic schools pop up like starbucks franchises, but your criteria of "A new med school to compete with the very best of the current ones" is the deal-breaker.
the initial cost to enter the sector of medical education (with the intent of competing with the big boys, rather than the osteopathic strategy) is staggering. its not like a law school where you just need a library, a classroom, and some attorneys willing to teach part-time. also, law schools can increase their class size (and therefore, revenue) with far less of a detriment to the actual education being provided. (ever wonder why there are almost 3 laws schools for every med school in the US?) to open up a big-time med school, you need state-of-the-art facilities, a library, TONS of full-time faculty to provide research/mentoring opportunities comprable to "the very best of current schools" (and you'd need BIG NAMES in science, again, to compete with the best schools--and the big names won't defect to your upstart school cheaply...), labs (for research and student courses in anatomy/histo/etc), clinical skills facilities, and the quiant little matter of finding a hospital to co-op with (unless you want to build a university hospital, which would be financially insane, but necessary to compete with the big boys).
overall, we're talking an entry cost of well into the hundreds of millions (if not beyond, what with a hospital and all). i just don't see it happening, man.
