If the rotation is increased, then I could see this being a very good storage and shooter-all-in-one type of mechanism. We played with an idea similar to this last year and called it a "dead stop shooter" because it accelerated from "dead stop" to full speed by the time the balls left the shooter.

The issue we had was that we inevitably still needed a loading roller to keep the balls in the robot and it ended up not being able to save us any complexity at the loss of range because the shooter was based much less on Ke.

Best of luck. Let us know how it goes.

Also wanted to add:
The designs used in 2009 (or 2006 for that matter) will provide good reference, but should not be emulated. Remember that in 2009 many teams ran 2-3 inches of compression throughout the system. It can be very difficult to create a spiral that can keep a constant 1/8-1/4 inch of compression (which is what seems to work for Frisbees)
