I might consider it, if it becomes an actual thing and results are shown to be good. The MIPO technique has been used with great success for over ten years, looks like, to repair fractures and do reconstructive surgery, but a quick search hasn't turned up any other references to using it for cosmetic enhancement kinda surgery.
In the meantime, if HRT and barbell squats don't do enough, there are always soft implants and/or fat grafting, if you feel it's important for you.
