I don't know if you can rename the origin planes or not. Never tried it.
But I'm not sure it's such a good idea to specifically name them Front, Right, and Top as this may create some confusion for people later on when you start assembling parts together. You may run into situations where you're constraining the Front plane of one part to the Top plane of another part and as I said it may cause some confusion. On second thought though, I guess I never really pay attention to the default origin names anyways, I always just highlight them and visually check to make sure that the orientation is the proper way I want it.
