I don't know if it would work. The air horn I had (max pressure @ 80psi) didn't sound any louder when I first charged it up, until very shortly before the pressure went out.
I didn't think about the freezing effect of CO2 though. We popped a couple of the smaller disposable CO2 canisters as teenagers and the bottles frosted over.
