Moxibustion flipping a big breech baby?

I am 37w 2d and at 36w 6d I found out my baby was 8pd 6oz and frank breech. Yesterday at my doctors appointment they told me that they did not want to try to flip him because of his size and I would have no choice but to have csection. I have been looking into alternative ways to flip a breech baby and one way I am intereseted in is moxibustion-acupuncture but I am concerned he might just be too big to flip in general. Has anyone had success with flipping a big baby with moxibustion?
