I actually had just the opposite reaction when I was at the double-header on Saturday. I thought that the horn sounded better at the park than on TV. With that said, I don't understand why they can't take advantage of that beautiful HD screen and show fireworks going off on that with the sound piped through on the stadium PA system after a HR and after a victory. I think it would work.
Awesome idea! Why not write it in to Feffer.
