Heh, maybe in GPOA we can get Gary to morph from muted or cupped to sans effects - do a "doo-waa" in the brass (and maybe a daa-oo as well!). Actually that's a pretty good idea. Must still be a few brain cells left that haven't punched out yet!
JABB's plunger mute trumpet and trombone sort of work this way. They don't use the morphing technology that is found in the Strad, but you can get a decent effect from a cc slider.
