The 8" solid wheels from 2010 (and 2011)? How would you fill those with foam? The best way to improve consistency is to have a system that works with a large margin of error. For example, our shooter puts sufficient backspin on the ball that it essentially drops straight down as soon as it hits something. This results rather lax requirements for the height at which the ball must reach the basket in order to score. Also, we have a shooter hood that has adjustable compression and angle. It is a bit late, but designing things like this into your mechanisms can save effort when you have to adjust things.

We used two wheels and couldn't change ours but we added two pieces at the top of our turret to ensure that balls entered the wheels at the same spot since before there was a good 3-4" wiggle room that they could enter variably at.
I don't know how your shooter is designed but if there's anyway you can make the balls enter more consistently I think that will be much more helpful in improving your shooter if you have a good squish on the ball.

In testing we noticed that if the ball was too far forward in the feed mechanism it would contact the shooter wheels just a bit longer than if it were farther back. This was enough to slow the wheel and ball down resulting in a significant loss of range and height. To fix this we adjusted the funnel to get more consistent feed to the shooter wheels. The consistency of the feed to the shooter is related to the consistency of its output.
