I though id throw this power and thought generating idea out for you to kick around.
Agreed, 397 did this PART of the year in 2008 to throw the Trackball and it worked pretty good. We eventually switched to using just 4 1/5" diameter 12" stroke cylinders to lob the ball the length of the field (Kettering Kickoff and WMRI) If you are curious about the arrangement of these I can find it and send you a picture. We were able to shoot it over the overpass from ~12 feet at 30psi. (In competition we ran at 60psi)

You may also want to consider the kinetic energy of a moving object is 1/2 * m * v^2. In a perfect world (which this is not) in a collision the energy from the kicker would be transferred to the object being kicked. Therefore you will get a lot more omph if you increase your speed. Consider using a lever to increase your speed.
