I use fox nitrogen charged shocks on my dune buggy... I took like 450psi just to air them up to take the load of the motor being in the back.... These shocks take alot more psi than you think. Unless you plan on having a commercial filling station on hand than you might want to rethink this idea.... These shock aren't made to adjust on the fly or by pushing a button. You can't just use an air chuck off your commpressor. The shop I use has fitted a nitrogen tank and use some type of one way valve with a pressure gauge. If you expected to go over 220 psi you might want to look into these shocks more in depth and find somewhere or some how to fill them.
PS.... I know you are trying to think out of the box but whats wrong with bags, you are talking about fabbing mounts, bars, etc --- Why not get a tried and true bag system?
