Good idea!! A "composite" Circuit Overseer Body! Like the Governing Body, a "composite." Seven would be plenty for a local Circuit Overseer Body, more if they need "helpers."
It used to be an average of 20 congregations per circuit. That's about 5,770 Circuit Overseers worldwide possibly now . Would save the circuits a lot of money maybe? Maybe not, these would soon be getting "green handshakes" too.
