Well it does look a lot like a synthetic art, but that's not necessarily a bad thing. Its definitely a legitimate martial art but I would like to know more about the Assiniboine and Cree elements. I have seen some Native American wrestling techniques, and there are numerous references to fighting skills throughout the ethnographies of North America.
The problem with Native American fighting skills is that they have not been codified and written down so no one really knows what was going on with them. It looks as though Lepine has decided to do just that. His codification has made it look a lot like Asian schools though.
It may not have been his prime motivating force, however. I think that the need for a sales gimic was the priimary force here.
