Well, I will tell you my experience, although I didn't use minkee, so that might make a difference. I made an adorable pieced flannel top, used fleece for the back, and no batting. When I quilted it, it distorted the top so bad, it looked awful, it was so bad I never finished it. I thought it was the fleece but a friend told me if I had used batting it would have been fine.
So I don't know, but it was very frustrating. Hopefully minkee won't do that. Good luck - it's very cute!
