Yeah, re-reading some of the books here, I am seeing a lot of overlap. A lot of cross-compatability too. It's not inconcivable for a fighter to take the Squire kit from the Complete Paladin's for example. It's actually one of the things I quite liked about the kits. They added some flavor to a class, without (for the most part) unbalancing things too much.
