True, but -0 motors blow through the thinking propellant disk at near full combustion chamber pressure, which CAN potentially eject something, theoretically.... It's strong enough that countermeasures of some sort are usually necessary to slow stage separation, like taping motors together or vent ports to exhaust the gases from the blow-through...

The problem is most rockets are traveling their fastest at burnout which will strip the chute in a normal rocket...

Still not the ideal solution to his problem IMHO but theoretically it COULD work...
