Absolutely! :-)

I thought about that when you said so before, but then I thought it was better
to keep the tracks rigid, otherwise the tension might vary in the round ends,
requiring good control of the tracks on the straight part. I guess you'd need
24mm pulleys and tyres on the inside of the oval as well as the outside.

Yes, the track is the bottom of the reservoir for 5 studs' width, so all the
balls eventually fall onto the track to be sent out.
There are solid walls either side of the track to prevent any balls slipping
past it, but if I lift the track far enough, a ball might drop below it and be a
pain to get out from underneath!
At least footballs are a lot easier to control than 1x1 round plates!

Here's a short video, one of my first having dug out my portable floodlight!

I didn't venture to walk around with the camera yet. The floodlight casts a
shadow, making the dark side of the model difficult to see anyway. It's hard
enough to remember my commentary for a few seconds - any longer video would
require a script and rehearsals! Still, the result is OK considering it's not a
movie camera.
A couple of other MOC videos are on my YouTube channel:
