Req: Better gun smoke

Is it possible to redo the smoke from the cannons to be more like the smoke given off by the smokestacks? It'd be pretty nice, because it would allow more for a cloud of smoke around the boat after you've been hammering away at a crippled merchant for a while. If the emitter type cane be modified to the smokestack style smoke, it would definately be a lot better looking and more atmospheric.
