I did the same thing with O2 regulators years ago for a home built O2
re breather. I needed the second stage because when the tank got low
the regulated pressure went way up and wasted gas. Setting the first
stage at 15 psi and the second at 3-5 worked great and about doubled
the time before the pressure spiked.

IMHO it should work just as well for keeping your acetylene pressures
stable.
