When I had my shop I had a person who did something along those lines. I simply wouldn't touch it. The fail safes alone are freaky enough. Many people use brass with high pressure and that of course is a big no no. Scuba tank valves won't work because you either have a yoke or din valve fittings and neither one of those regulate pressure. So you'd have to build a valve block that screwed into the tank allowing a PB reg to screw at the crown. One of the few ways I've seen it done. I wouldn't do anything of the sort, and me going to school for the Fire Dept I've seen the way those tanks are treated, not that gently. Also keep in mind the hydro dates and life cycles of those tanks. If I'm not mistaken large carbon fiber tanks have a 15 year cycle from it's original hydro test date. Hope this helps
