I can tell you with almost total certainty that you want to be thinking about a part-time program, rather than a 1-year accelerated full-time program. Not only is your GMAT score going to keep you from being competitive at the schools you listed (you likely need a 670, at the minimum, to realistically take a run at those programs), but your age, career position, and goals all indicate "stepping a rung up the ladder" more than a career transformation. I assume from your profile that you are in a metro US city with access to some top PT programs and I'd strongly encourage exploring those. After all, they exist for a reason! To service candidates like yourself. You can even consider EMBA programs if you can make a case that you are in an executive type role and in need of MBA frameworks.
Hopefully this helps.
