Yeah I thought of doing that however around 27x mixes is as far as I can go to bring the rear chamber pressure close to the max peak chamber pressure. This is because the scuba tank I'm using to fill it will be around 3000psi (when full) which is the max I can fill the rear chamber, and the front chamber peak pressure will reach a max of around 3100psi at 27x. Technically I can still fill the rear up more than the front for higher mixes, although it won't be very near the maximum peak pressure. So as the mixes goes up, the efficiency of the piston valve goes down. Unless I can get a higher pressure tank of course.
However if I use this concept along with plenty of ignition points, then we should be all good.
