Hi there,
I understand your concerns with your outcome from your prior surgery, and that you would like to achieve more tightening of the buttocks and thighs. I'm not sure I agree with you that this would only be possible through the more radical approach you describe though, as the traditional approach to body lifting is usually extremely successful in addressing these areas, even in patients with extreme amounts of loose, stretchy skin.
In addition to probably not being necessary to achieve your goals, the approach you describe would put you at high risk of having a scar that creates long term discomfort when you sit, and the greater potential for injury to your Sciatic Nerve (one of the largest and most important nerves in the body); that's why you haven't been able to find a surgeon who would do this. I would return to your original surgeon and review this with them. See if a revision might make you happier.
