profile eval - not sure of chances

I am hoping you could help me understand my realistic chances for top schools. I am a year out of law school, practicing with a mid-sized regional firm in the southwest. I had a 3.4 gpa in law school from a public school. I had a 3.5 gpa from a private christian undergrad. I took the GMAT and scored a 720. At 28 I have 3 years work experience plus the 3 years I spent in law school. Do you think it is realistic to shoot for harvard, stanford, tuck, or columbia? How do b-schools look at attorneys in general, is this a plus for me or will it hurt my chances. I'm hoping to change career paths. One of the aspects of professional life that has always been a motivating factor for me has been leadership opportunities and responsibility, along with upward mobility. It is clear that firm life simply does not provide this, unless your name is on the building. I think my skill set would translate well into industries with strong legal bents, such as regulatory work, private equity, and m&a. Do I have a good shot if I put together a solid app with great recs and essays? Thanks!
