Personally I think it could be a good excuse to learn pneumatic systems and a good practical goal for teams who haven't used them before. If weight is your issue one or two plastic tanks and the smaller compressor should be no problem. That said making a bracket for a servo to replace the mount for the cylinder doesn't seem hard at all as I look at the CAD. One thing I haven't seen however is the potential use of solenoid actuators for shifting and that might be something to look in to as a pneumatic alternative.
