I can't say that the team has committed to using this, but one non-pneumatic mechanism that came out of the brainstorming was a shooter mechanism similar to those used in Aim High. Think of a wheel, maybe 6" in diameter, spinning fast. When it comes in contact high on the ball, it puts a heavy top spin on the ball, which then rolls away fast. Get the angles right, and maybe make that wheel move up or down a little and you can kick it into the air, or roll it fast enough that the Bump does the airborne part for you...
