Could Bruce Jenner have won the 1980 Olympics on the female side if trans-womanized?

 Mississippi making it illegal for trans-women to compete in female sports events raises an interesting questions about the sportingness of trans-woman taking over female sports. Is there a substantial degradation of physical abilities in cutting down from male to female as in the case of the 1976 Olympic decathlon winner for men Bruce Jenner.

If Bruce Jenner had surgically and chemically transformed himself to a neo-female just after the 1976 Olympic  he have won the 1980 Olympic decathlon as a woman competing in female events?

What about other great athletes; could Wilt Chamberlain have played in the female N.B.A. if trans-womanized, and would he-she have been any good?
