I think you would have a shot at your target schools with your profile. Having a seven year consulting background will be valuable as a classmate, so what you bring to the table should be attractive to the admissions committees. Additionally, your strong GMAT score coupled with your Master's and undergrad degrees tell them that you can handle the academic rigors of a top flight MBA program. You are actually a little older than most b-school applicants, which can be couched as an advantage and potentially even a diversity play (older, wiser, etc.). Make sure you cast a compelling vision for what you want to achieve post MBA and why now is the time to go back.
