I strongly advise against this. Never ask a surgeon to do something that he is not comfortable doing. Your odds of getting a good result are much better letting a surgeon do what they want to do. Telling a surgeon what to do often leads to medical disaster as well as a bad relationship with the doctor.
It is perfectly legitimate to tell a doctor what your concerns are. If he cannot address your concerns in one way or another to your satisfaction then it is your responsibility to find another doctor.
