I agree that the chance of an acceptance this season isn't worth pursuing, but I disagree about your research, shadowing , and clinical experience being average. You didn't mention nonmedical community service, teaching, or leadership, which are other ECs you might consider with the extra time before you'll apply.
You could consider the do-it-yourself postbac. Just by getting your cGPA to 3.4 and getting an MCAT score of 33+, your odds of an MD acceptance more than double. Also, if you haven't, look at SDN's Postbaccalaureate Programs Forum for additional options besides Wake's.
If you are unaware of the DO med school option, then I just wanted you to know that their application service (AACOMAS) only includes the most recent grade among retakes, provided the credit hours are the same or greater. Your GPA could be sufficiently competitive as you are, and you might gain an acceptance with an MCAT taken this season as you originally planned.
