Diffusion kills brightness. From some distance it's impossible to identify individual LEDs on a 144 LEDs/meter LED strip, saving the diffusor. You've already posted a video - did you try this outside at daylight already?
Handling a baseball impact, I'd say the plexiglass itself should be strong enough, without an extra MDF backplate. I'd prefer a more lightweight build. Milling the MDF is a lot of work, even using a CNC.
