Yes, but that results in less ball energy at the same launch speed. There's the extra friction given by the cowling and the lack of energy from a second wheel. If you're aiming to hit a goal from a distance with any accuracy, you'll need to have more energy in your system to hit from ~20' or more than a single CIM or similar motor can supply.
Also,
this.
