I don't really agree with that. A lot of people that are near the top of the industry have gone and can go indefinitely without going full hardcore and have done well doing it. Whether she can or not I don't know, but it's not impossible if somebody is a quality model.
For the sake of argument, hypothetically, even if that was the case there are better ways to go hardcore than others and better people one can associate with in the industry with than others both in front of and behind the camera.
