I imagine the wind from the ball passing through would disrupt a sheet of fog too much to see the pins bounce around, but it would be cool to see 10 narrow columns of tightly collimated fog with pins projected on them. Maybe there's a big sheet of glass suspended at an angle around the last quarter of the lane. The ball rolls under the glass into darkness and is visually replaced seamlessly by the virtual ball shown on a screen hanging on the ceiling, facing away from the bowlers- a Pepper's Ghost effect. The first issue with this of course is that it would only work from certain angles; the possibly larger issue is that you'd have people rolling bowling balls at a giant sheet of glass.
