Jack Burns and Jerry Van Dyke

I wonder what it would have been like if Jack Burns(Warren Ferguson) and/or Jerry Van Dyke (Jerry) had been invited to play Barney's "Deputies" in the movie? I know that Andy barely tolerated Warren, but I wonder how he and Barney would've hit it off, especially since Warren came in after Barney went to Raleigh (Don Knotts left the show)?
