I didn't think I would respond to this because I really disagreed with the basic assumption of this thread -- but I feel I must respond now if only because my dear wife has "used my name in vain." 
There is an assumption that I believe exists for PADI courses that they aren't really comprehensive enough. I believe that is wrong. When taught to the fullest, it is my belief that PADI courses are extremely thorough -- especially the "Specialties" that so often are dismissed as fluff. One case-in-point is the PADI Boat Specialty. IF the instructor actually follows the whole syllabus, the student will learn a LOT about boats and diving from a boat -- including boat handling and care.
So when the question comes up about teaching "over and above standards" within the PADI system, I contend one doesn't need to at all. All the instructor needs to do is to teach the WHOLE syllabus that is provided and there will be a great course.
(Off topic (sort of) -- my "Techreational Workshop" caused my LDS some huge concern when first proposed but PADI "blessed it" in no small part because it was NOT a course. I attempted to teach it once and the response was so underwhelming I haven't tried since -- but maybe soon.)
