John,

That is exactly what I am planning. I am going to install a cam in- 
between the two front Canopy hinges, that will pull pins out of the  
two forward modified separable hinges. As for the Canopy sliding back  
and decapitating me, or just taking out my teeth, I plan to install a  
hinge on the rear of the canopy for it to pivot up and back on. Some  
kind of hook that you engage, or a hinge made of chain link with a  
pin you can put in before takeoff. I am working with a Parachute  
company to develop a parachute that you don't sit on, (I want  
comfort, and no excuses not to wear it) You will have the usual  
harness straps, but the Chute Pack will slide into a pocket behind  
the seat and down at a 45 deg angle. They said they made something  
similar for another plane.
