Jumbo-D 02 cyl. with retreaded valve

I have a few ems 02 cylinders,,hmm, I was thinking a "Jumbo-D" has a 17 cu. in capacity @2214psi 5.3in. dia. 13.3inhes long. Could one turn down and re thread a scuba valve and use said combo for rebreather use?

We did that a few years back for a client. Only problem was the valves came in without a saftey assembly. Hence we could not sell them in the USA except to military who were exempt from DOT rules. Suffice to say i have a box of them ....... The main problem was getting the right oring for the boss of the valve fitting to the bottle. It takes a little tweaking. I've been using them on some wrap bottles seem to work well.
