It already doesn't make sense that Mewtwo gets a Mega anyways. It can be assumed that [Pokemon]ite, Mega Stones, occur in nature as in XY they were talking about how they 'discovered' it. So why would an artificially created Pokemon react with a naturally occurring stone the same way as other naturally occurring Pokemon?
Also, that's why i chose this image. You wanna see the next best image I could find? Here.
