Perhaps something other than CO2 might be fruitful here. Halons work,
not by smothering the fire but by reducing production of radicals
involved in flame propagation. If the chemical mechanism--the
step-by-step sequence of molecular collisions--of the N2O-C2H2 reaction
is known, perhaps an additive could be found that interferes with the
rate-determining step.
There are at least two problems that I can think of, right off the bat.
First, that additive would almost certainly interfere with the desired
reaction in the combustion chamber. Second, the decomposition of
acetylene into its elements is a spontaneous reaction (delta-G of
formation is positive). If an additive that would prevent that from
happening was known, it would probably already be in use in acetylene
used for welding.

effective solvent for organics. The partnership with something like acetylene
will be quite an intimate affair and I just can't see CO2's pacification role
producing anything other than a subtle reduction in explosive yield when the 2
energetic compounds inevitably get down and boogie.
