An SMP makes sense if you're in the 3.0 range. It doesn't make sense if you're well below 3.0. Doesn't matter how high your MCAT is with a way-below-3.0.
Your path to an MD school has to go through another 2-3 years of undergrad. If you can roll another 35 (your current 35 will expire) you may be able to apply after 2 more years, assuming a really high postbac GPA.
You'll want to consider becoming a TX/MI/LA resident, because those states' public med schools either offer academic forgiveness of the last decade, or they emphasize your last 2 years of coursework.
I guess you could look at a DO app after a full time year of undergrad, but understand that even DO schools screen on cumulative. DMU rejected me for a cumulative 2.994. You can also look at the 1-2 year masters programs at DO schools that feed you into the DO program.
Best of luck to you.
