Can I request the Chairman to reinstate me if I get fired?

I am only an employee. I emailed directly the COO of my corporation what are the chances for me to get fired? It is a 3 Billion dollar corporation. The email is about a revolutionary improvement that could change the future of the company. .( I make 9/H). I was told in the past that if I don't follow the chain of command I will get terminated.Can I send a request to the Chairman to be reinstated and start trying my suggestion to turn around our corporation?
