I'm somewhat an optimist, so I hate to say that you have absolutely no hope...we don't know, we're not adcoms, we're pre-meds.
Unfortunately, your current GPA is the problem, and I'm not sure how many classes you would need to raise it up to be more competitive.
Have you considered going for a second bachelors degree in a hard science? You are probably looking at at least 2 more years, but maybe that could help.
A master's degree unfortunately doesn't figure into your GPA for med school even if you did get straight A's.
Even though I understand your desire to go the MD/PHD route, I think that might be even more competitive than the regular MD route. I just think that it might be a little out of your range. What I would do, is to research the schools that you would like to have applied to...make a list, and for each school, look to see what they would require for acceptance. Maybe there is one that is more open to your educational research to date.
The other question you need to ask is if you want to be more of a researcher or more of a clinician. If you want the former, maybe just continue working on a masters and trying to get into a PhD program. If a clinician is more what you want, seriously consider DO. You'll still need to bring up those grades, but it is possible. Once you have the DO, you can still have some research options, it just won't be as a PhD.
You need to decide what is important to you.
Wishing you the best in your future
