Not to put you off but I don't like the idea as to me it makes it more venerable to rupture and failure.
Think of a flat balloon. Take a fork to a flat balloon, pretty boring as bat shit. Sure might put a whole in it but nothing happens.. Now blow it up and take a for to it.. And Im pretty sure I read that the average balloon is sub 1psi above atmosphere.. Now you wanna put 100psi into steel..

Just food for thought.
