I think it might be worth it to at least investigate using something similar in the NFL. The ejection and being subject to future discipline might deter the behavior.
The big addition this year is basically you can't target someone's head and still get the ball on a turnover. That's automatically reviewed as all turnovers are, and if they determine it was illegal the play no longer stands, ejection.
It's a very subjective play, but seeing it on replays at least helps point towards more accuracy.
