I think you're targeting the right range of schools. Yes, you have an interesting profile - however, the GMAT is still an issue, and no matter what schools say about "accepting a range of scores with no minimum" the reality is since the overall caliber of applicants applying is so strong (yes, you're interesting, but there's also enough other "interesting" folks but who will have stronger GMATs than you) - you really need a solid score for it not to be a concern.
You can get into these schools with the score you have, but you're a little safer with a higher score. If you feel you're a strong writer and storyteller (i.e. your essays will be great without having to spend the considerable effort that others may have to), then it may be worth squeezing in another GMAT retake. Again, your GMAT isn't putting you out of the running, but it can put you on the margins for schools in the top 16.
