hero ability on defense

so now with the feature of live replays and the few past requests of using the hero's ability on defense, it got me thinking.
what if when we are able to view our village being attacked during a live replay, we would be able to view and trigger our hero's ability?
some requests in the past have mentioned an automatic response.
that could be a bit ovepowered since it would happen every time
but this would only be in affect if you catch the live replay.
you would trigger your own hero ability

i scrolled through the ruled out ideas and did not see this there.
if i missed it, simply point it out and fine.

thoughts?
