We have supports under the ball and these rollers on the sides of the ball (near the middle) so it is not like the rollers would be supporting the weight of the ball directly. We pick up off the ground.
All of your points are valid though.

Keep in mind a roller system will slow down when it makes contact, I guess how much would all depend on what the object is, if it is being compressed, etc...
We had a roller this year with two sides, one side powered by a 540 and one by a 550. It slowed down a significant amount when a ball was contacted.
I would use these motors in an application you might use a servo, but need more power. Maybe a little blocker to block the ball path of a conveyor for a shooter in 06.
They might work as a roller, but they game piece would have to be much less formidable than a trackball.
