My impression: this would totally fool the average person, and probably it would fool also me when I’m not paying close attention (not sure about my piano teacher). But you can still hear some small differences. Also, hearing a youtube video is not the same as hearing the real thing, because even the acoustic piano sounds more similar to its electric counterpart given that you’re hearing a recording anyway. I suppose that the difference would be bigger when listening to the instruments in person.
