I would vote that it is a bad idea, though it is hard to think of a way that this would actually hurt you, the potential is always there to rub people the wrong way. But, more salient, I don't think that it will be productive.
Simply put, in medical school admissions, unlike job interviews or even residency interviews, you are not compared directly with other applicants. Yes, every once in a while someone will make a comment in committee, but you aren't put side by side. You are compared against class averages and what the general profile of their students are. If you want to know how you stack up academically against matriculants, buy/consult MSAR (which you should already have). For all the other components, feedback from SDN/mentors is going to be just as good frankly.
