it wouldn't do the trick. the CO2 needs to be very finely atomized into tiny, tiny bubbles to dissolve into solution, which is why soda water is put under pressure. When you twist off the top, the pressure is released and the compressed CO2 expands rapidly to create fizz and foam.
This is also what happens when you get the "bends" from diving. The gasses in your blood at depth are under great pressure, but it you come up too fast, they expand and create blockages in your blood vessels and all kinds of other awful stuff. You either have to come up very slowly, pausing at specific depths and waiting, or come up fast then literally strip and run into a hyperbaric chamber and do the decompress in there on board the ship.
