How do I start my own martial art?

I've practiced various martial arts like Kenjutsu Judo Kickboxing Ninjutsu and Jujitsu. I want to create my own martial art using my own style of all these martial arts above by incorporating various techniques but with my twist. I would like to call it Kashikoi Senshi meaning Wise Warrior. Mainly I would like to teach how to use the human bodys weaknesses to your advantage in any particular fight. I have techniques for katana's staffs or just for you hands and feet. Basicly knowing the best possible way to bring down your enemy with whatever you have at the time may that be a katana or your fists. Do I have to have black belts in all these martial arts before I can even think about doing this?
