They tried to do this about 20 years ago with "synthespians". The idea was that you create a digital persona and have it play in several, unrelated between them, films, as if they were real actors. It was tried in the movie "final fantasy" with the synthespian "Aki Ross", who was the lead character. But it did not go anywhere.
