I think I have to disagree. To take off the limit would be to say that the end justifies the means. I think part of being a light side jedi means you won't resort to extremely malicious and cruel acts. Therefore powers like force crush and kill become out of the question. As far as dialouge I think light side jedi should be able to use force persuade in some situations without taking a dark side hit. But as far as specific powers I think the system in place is just about as good as it's going to get.
