The goal of an adcom is, among other things, to get a class full of people who will make it through the curriculum, pass the boards, and become licensed physicians. You might think that grad school is good preparation for med school, but it isn't. The skills you need to succeed in one versus the other are not even located on the same portion of the planet, never mind overlapping one another. Medical school rewards people who can learn massive amounts of information and regurgitate it. Anyone who tried to get through grad school that way would flunk out. Conversely, many successful PhDs who go on to med school struggle mightily for the first two years. The kids who came straight out of college and just spent the past four years doing nothing but memorize-then-regurgitate can run rings around them in the classroom, and they do.
As pseudoknot already said, most physicians aren't scientists, even though they know a lot about science and they use science to do their job. Grad degrees are not the way to go if becoming a clinician is your ultimate goal. The purpose of a grad degree is to get training for a career in research, not to serve as a stepping stone to med school for people who didn't do well enough in UG. (Note: I am saying this with the caveat that SMPs do not fall in this category, since these degrees, albeit graduate degrees, exist for the purpose of getting people into med school, not teaching them to be scientists.)
To answer the OP's question, no, your grad GPA won't make up for your UG GPA. If you don't get off the waitlist, you might consider adding on a lot more schools this time around. 15-20 should be reasonable. Your MCAT is about average for allo matriculants, and your UG GPA is below average. But it's not prohibitively low if you apply broadly to schools that take residents of your state and whose missions match your interests. Best of luck to you. 🙂
