If we can't do this, then the argument must go "Stimulus-->Response-->Filter" where as the response (epigenetics) is only the middle step from stimulus to new species. The cause is clearly the stimulus, and the end result is clearly via natural selection (Filter). Again, via computer science, the filter is the only thing that matters in the end, because we only care about what gets left behind...-Agreed. But I think it will require direct stimulation of the epigenetic mechanisms. If the organism is threatened, there are probably somewhat slow chemical mediators to turn on the epigenetics, and that may confuse the results of your proposed experiment.-By the way: Cru du Chat? please translate!
