The first thing that jumps to mind is an entire pinball machine like the mini-playfield on Twilight Zone. I don't know how hard it would be to make the magnets strong enough. The pinball machine could be smaller, maybe a bit smaller than a cocktail pin.
And of course, there's the paddle from the mini-playfield of The Shadow.
Now I'm envisioning a mechanical amusement where instead of a big paddle you move back and forth, there's a row of piano key-like paddles with solenoids that you can can use to bounce the ball upward. Maybe controlled by a piano keyboard.
There's also Screwball Scramble and Labyrinth. I would consider those to be pinball-adjacent. So tilting something to move the ball could be fun. Of course, there's Rat Race.
Pitch and bats are cool, there could certainly be more variations on that concept. I think I saw one that had a golf club instead of a baseball bat.
