This program is known as an academic enhancer so that can work in your favor if you are looking to enhance. However, if you feel unsure with what route to take, you need to look at every option possible. You can either retake classes with poor grades and do grade replacement via DO, you can do post bacc classes has to be a good 20+ credits/hard sciences and much showcase 3.7+, you want to show improvement not the same undergraduate performance and since you're from MI--so am I, your post bac in 20+ credits will be well favored and even replace your science uGPA at Wayne State and MSUCHM; both verified from admissions counselors there, enroll in a post bac with a linkage aka VCOM or Temple, those come to my head, or you can get a degree in graduate studies specifically SMP and UMich's program is this or even Wayne State. You have to look at your options for schools as well, there are some schools who really prefer the post bac classes as it does show improvement. I think it would be a good idea to focus on your uGPA more than enrolling in a graduate program at the moment because you need to fix what needs to be fixed and if you think your uGPA is low, then focus on this first; it'll show case improvement for both MD and DO, it can raise your uGPA, and it'll give you time to enhance your application on anything you think you are lacking! I personally think your GPA is not so low as well, there is definitely still time for improvement.
