I would guess that is what OP meant? Grind off every other tooth....
While its certainly possible to do, and I think it would still function (if done properly) it wouldn't be very noticeable.

At another time and place the discussion turned to customized bikes and polygonal sprockets. From that the concept of "Pants-Eater, the biggest 14-tooth cog in the world" was born. (pic below)
I never bothered to cut one tho', so I don't know how well it would really work.
The chainline is correct however, and it would be equivalent to a 42-tooth sprocket.
