I really do not think what you’re suggesting can be done. It all comes down to contractually adhering to the rules put forth in the guidelines of governing bodies. Everyone who participated knew that only the top three finishers would qualify for the Tokyo Olympics. That is the structure of selecting participants here in the U.S. USATF cannot strip the victory unless there is some sort of catastrophe or pandemic clause. Also, all of the standards, qualifications, etc. have been set for the Tokyo Olympics. Whether they are held in 2020 or 2021, they must remain unchanged unless there is a clause in the guidelines.
