I also think it's not about the age (although it's a factor), but more about all that experience in one field, and the reason why you'd want to get a full-time MBA. Basically, at a top 10 school, there are literally thousands of younger, accomplished management consultants, and you'd be competing with them as far as professional background goes. If your future goal is, for example, change careers to finance, PE or VC, then there are even more younger applicants with similar profiles.
I'd say you'd need a pretty damn good 'wow factor' to convince adcoms at top 10 schools to accept you instead of others. Your professional experience, no matter how accomplished in your field you might be, definitely is not.
Maybe you should ask yourself if you really need a full-time MBA to achieve your goals. If there's any other way to achieve them, maybe you should pursue that path.
But that's just my opinion. Of course there are people in their mid-30's at Stanford, Wharton and Harvard. But they represent probably less then 1% of the class.
Good luck anyway!
