Ed,
I'm sure that RRS, Markins, Kirk and others will offer you a universal lens plate if you approach them.
I've got a Markins PL-55 lens plate which I believe is considered to be a "universal" plate.
If you chose the specially designed Q3 clamp with the screw knob, I'm pretty sure that virtually any of the manufacturers plates would be useable.
My two concerns about trying to use just the one plate for a variety of lens are a) The inconvenience of constantly having to swop the plate between lenses plus the wear and tear involved. And b) The very "universal" nature of the plate means it cannot be designed for best balance on all your lenses. Some of the long tele's have longer than normal plates to allow the camera and lens to sit on the tripod in a state of near balance.
