I don't think many people have been in your situation before so you may not get much advice. Plus, what the director at one program thinks probably doesn't translate into what another director thinks. You're in a unique situation and you can make it work for you or you can make it work against you depending on how you are able to articulate your experiences and how they've led you to this path. You will stand out and I think and lots of places will appreciate that. Every school looks for something different and that's why applicant x with a seemingly perfect application will get an interview somewhere and rejected elsewhere.
But you won't find a list of 25 other people who have done this and have definite "yes, this helped me" or "no, this hurt me" perspectives. To me, it sounds like you need to be more confident and secure in the narrative that has led you to apply md/phd and not worry about how one school views your life choices. Relax, enjoy the ride.
