In your knife edge demonstration you could measure this if you rotated the

I *believe* it would show you were in coordinated flight.

Didn't even have a ball indication in that airplane. You don't use them
in aerobatics. Even for primary instruction, it's best to get the
student's head outside the cockpit and away from the ball as soon as
possible and concentrated on nose attitude where it belongs.
Personally, I feel the ball is the least necessary instrument on the
entire panel :-)
