Well you have a really fantastic background - with depth and breadth (and of course the fantastic grades to go with it), and I think that with an artful story you can have a shot at HBS 2+2. What's also good is your non-traditional trajectory - because most HBS 2+2 folks are not the typical business folks you see in the regular program (basically because they can get in later anyhow)... so your unique story becomes all the more relevant.
Oh yeah, and having a brother as an HBS grad helps.
I think the "tricky" thing in your profile is to figure out exactly which story to use and how - because you have several possible directions given the breadth of your interests, and to take everything and as you wrote "weave" it together into something homogeneous and cohesive.
Just keep on working on your profile (and yes, be nice to the head researcher at Columbia!
PS will you be applying to Stanford deferred and/or Yale Silver scholars?
Best,
