I should add that there is no test where they have "reinfected" someone or something else using tissue from someone who has tested positive. This includes animal/bat tests. If I found such a test of course the bar for believable evidence would be damn high.
I forget the name of the 1900 scientist you're drawing from, but all of his ideas have been replaced. There's not an ethical way to implement your suggestion, for one. Of course it's not ethical to deny sick people medicine. Everything done is a violation of ethics!

Injecting a virus into a test animal is fine. Claiming it can or cannot crossover is separate.
Coronaviruses typically are quirky in cross species infection. The test is meaningless.
