With your GMAT, Solid banking career, and grades you are definitely off to a good start, and can apply to any top program with competitiveness.
To set yourself apart from the mob, I wouldn't seek any crazy fancy tricks in your case. Just show them that you are good, very good, maybe even the best. That you have been super strong in every workplace, that you have worked on huge projects, and gotten amazing results. They will speak for themselves.
Your school list is great. With your stats, no reason you should aim any lower.
Now just beat the heck out of those essays!
