Acoustic rocket engine

I wonder if it would be possible to construct an entire propulsion system using only acoustic tech. One would maintain superchill for fuel like RP-1 using thermoacoustics... Since principle of acoustic ignition is also based on shockwave passing through a gas, could the same system be used to both cool propellant & later ignite it? If you linked these two systems via something like NASA's Bellocq Compression Wave Pump could you cool the propellant, keep it under pressure, pump it to the ignition chamber, and ignite it all using one (acoustic) system rather than multiple systems? I'm picturing a much-simplified engine, somehow, with only one major component, although I haven't had enough coffee today yet that I can picture it playing Van Halen in the parking lot... I suppose something much similar could also be used as a naval torpedo, although it would probably drive sonically-sensitive sea creatures--such as whales and dolphins--nuts. Lord knows it might spoof up a sonar array...and come to think of it might also tend to do interesting things to a sonic boom...
