Again - that's a lot of effort for something that may not be advisable
because of the pressure differences you stated. Jury rigging
something could result in any number of things from singed hair to 3rd
degree burns. You might not be very popular with campground neighbors
if you burn down a table or tree.
I wasn't sure about the pressure, but now that I think of it the stove
I used earlier this month did note "16 PSI" on the neck of the
connector to the cylinder. Must have been regulated to prevent it
from flaring up. I looked it up, and apparently propane pressure (as
with any other liquefied gas) is heavily dependent on temperature. In
my use the pressure might have varied from 70-1140 PSI.
Seriously though - consider bringing along a few of the 450g Primus
canisters. It should last you plenty long. If you're going to be
near any major cities, maybe map out where there are REI stores that
will stock several brands of the Lindal valve cartridges.
