Servos are a very bad choice because you will be shifting at top speeds. Servos have very little output torque, as compared to a piston. Also, designing the system with pneumatic pistons would be very easy!

You just need to have a pneumatic tank, valve, solenoid, all the basic components. You may be able to run off an external compressor, and precharge the cylinders!
Some teams don't like using pneumatics because of the weight. If you are just running shifters than it may not be worth it.

67 has been one of these teams in the past. They have used the window motors instead of servos to successfully shift. You cannot shift on the fly, but it can also be lighter than a pneumatics system.
