Colebatch, I've been working on Gas pressure shocks for 40 years starting in the '70s while racing buggies in Baja. I use Air instead of Nitrogen. Even though the manufacturers like to use 250psi or so, in most cases 125 to 150 is adequate.
I have even taken to sharpening the sealing V of rubber seals with a 1/4" hand drill motor and a rotary stone. I do it on Fork seals and the monoshock seal of my street bike.
I do it because I'm cheap, but more to test my theories. I always imagine that I'll be somewhere where I can't get parts. Irkutsk comes to mind as a good example.
.....so by using the seals over and air to refill the shocks and diluted, with mineral spirits, 30weight oil, a field service is not too difficult.
Best to get with Prutser for a practice session first. Think removing the seals with air pressure or hydraulics to keep from hurting the seals.
And those plastic Seal Mates will fix your leaks 50% of the time.
