Crothian said:Well, Mongoose has class concepts that are similiar to kits in all their Quint books. But other then that I can't think of anything.
If you want something that doesn't require to wait until mid-high level (PrCl) and immediately goes beyond the simple selection of feats and skills, Crothian gave you a good advice to take a look at some Quintessential book.
They basically use the DMG original idea of tweaking the core classes by adding something in exchange to something else (see the DMG example about changing the Ranger into a Hunter of the Dead). It should not be difficult and should not require playtesting - other than try using the class immediately - since you are not rewriting the core class completely, just replacing or changing a couple of things.
I would suggest however to use Mongoose's examples just as suggestions, because they tend too often to be just a "get +2 on this few skills and lose the bonus feat" without real significant change, probably because they were too much cautious.
