If you were doing this for fun, you could use a 5amp breaker and 22awg wire safely. As you pointed out, it isn't safe to use a 20amp breaker and 22awg wire.

Joe is correct, look at the rulebook first. especially the sections he has quoted above. It is a good idea for your electrical person to print off the few pages with wire gauges and breaker requirements and keep them at his workstation while wiring.
