Just to echo what John said for a minute - 1/8th on a shooter is indeed way too much material. We made our whole shooter out of solid plates of 1/8th sheet. Way too beefy, and it raised our CG way too high. The main concern with your camera mount will be to mount the assembly so that it is rigid enough that the high speed wheel behind it won't make it wobble too much. As long as you have a rigid cross section you can take out a lot of material from your mount and it will do just fine.

Depending on your design, you might benefit from making the back plate of your shooter a little differently. Especially with a single shooting wheel, having some structure to help keep balls aligned is really helpful for repeatability. Here's a picture of Miss Daisy's shooter. They have a similar plate-and-standoff design to your own shooter, but they also have some inner plates to help guide balls down the center of their shooter. You can make this out of thin material since it's even less structural than the sides of your shooter and you should get a bit more of a repeatable shot.
