I tried that on my 05 bot, and wasn't too pleased with it. It takes a bit more tuning to get the drive system to shift evenly, which makes driving a bit of an issue. Plus, each cylinder is a half inch stroke, 3/4 inch bore, so the air useage is minimal.

Yeah, these are 24 dp gears. The pinion and the first gear are 20, as that is the gearset that ends up being hit with the most force and wear in a drive system of this type. They'll work just like 20 dp, but they're smaller.
