I have no idea if this is even feasable, I am a total user type interface gamer, the only code I know is the combo to my padlock for my locker. Can DM/World builders create subset classes like they do subraces? I see Goblin swashbucklers, etc, is it possible for PC's too? (I am not talking about the already existing PRC's, something entirely new, or an old calss or PRC tweaked into a new form :?:

I am almost certain that this cannot be done without a HAK.
