I'm intrigued with a lot of these somewhat novel ideas you are presenting, as I believe the next advances to come in the treatment of stuttering will be holistic in nature, related to the mind-body connection. I intuited even as a young kid that speech therapists don't understand the true extent to which stuttering operates; their therapies seemed too clinical and not comprehensive enough. John C. Harrison was the first author on stuttering to really jailbreak my mind from the limited paradigms I was taught in speech therapy. If you haven't read his book, definitely consider reading it. I'm working on my own theories right now, of which I've been able to make progress with my own fluency.
