Crossbow like ball launcher

How are you planing to load the balls? If you don't have a loading mechanism I suggest that you figure that out first.

Just my 2c here.

Be careful about complexity. My team still runs into things where we take real life scenarios (Crossbows), and then try to translate them into robots. I think your difficulty will come with a latching mechanism because they are inherently harder to get working (Holding 100lbs force but using 2lbs to release).

I don't know how advanced your team is, but a "Ball pitcher" will be a lot simpler mechanically because you just feed the ball in and boom its away.
