I think that Stern and Wharton might be too much of a reach given your (current) stats. BC and Georgetown would be better reach schools. Also, you might have a better chance at GU and BC getting in to the A&S school and majoring in Econ. That way you could get the liberal arts plus the Econ major (and in the case of BC A&S students can take up to 8 classes in the business school. Just a thought as the B schools there are getting harder and harder to get into. UMichigan might be another reach school to check out and Indiana Kelley could be a match (I know less about the latter 2 schools).
