would it make sense to put an adjustable hop-up (machine screw) in a small tennis ball launcher like this?

Pretty much the same as this, but w/ 2" chamber & different valve placement

Ok, I got the picture, also, at what point (as far as temperature) would it not be safe to use 2" pvc w/ a pop-safety valve set for 95 psi?

Ok, thanks. I actually just finished the first of these 2 guns, they are for my little cousins, and they are way more fun than I expected. I have been shooting tennis balls at the pillow in my room for the past 30 minutes.
