I would have to check and see, it depends on what speed is desired which would dictate the gear size. The two stage system allows for chain inside of the tube as well as making it easier to change the gear ratio, because you do not have to worry about the sprocket hitting the cim.
It is not seen well, but half of the shaft on the gear next to the cim pinion gear is covered by the cim. So the gear would have to be very large to make space for the sprocket and I don't think the sprocket would fit.

Maybe run the first stage with
belts?
