Hi there "Hmmm IDK" (love that name...)
Interesting challenge you're posing for us! The key, in my opinion, will be that GMAT -- 720 and up should be your target, and from what I'm seeing here, that's probably realistic for you. The thing about a low GPA: it either results from maturity problems or from lower analytical ability. A high GMAT will narrow the schools' concern to the first option, maturity.

You have done excellent coursework since your shaky undergraduate start, and built an upward arc in your grades, so you can make a strong case for improved maturity. A super-high GMAT, both verbal and quant, will provide the support your case needs. That frees you up to focus your application essays and recommendations on showcasing your other assets: job growth, leadership, goals, etc.

What top b-schools can you target, assuming a best-case scenario GMAT? Many top programs are forgiving of slow starts, although Harvard is probably off your list, and Wharton tends to do what Harvard does. So once you have a GMAT score, you can start exploring schools using that as your basis. Visit each school, visit the admissions office, talk to them about your GPA issues. No admissions representative is likely to say "forget about it" in so many words, but you'll sense that some admissions representatives are giving you more tangible advice than others. This will help you get a sense of who's interested and what you might need to do to win them over.

So, not a lot of concrete feedback at this stage -- get that GMAT out of the way! Then we'll have a better idea of where you stand. Feel free to reach out for a free consultation, by the way, where we can go into these issues in more depth. https://www.stacyblackman.com/contact/
