And you expect to fly a PBY at that slow speed and with little maneuverability in the ack of a carrier task force? 5 inch guys will have a turkey shoot. The torp carrying PBYs went after shipping, as in merchant ships mostly at night, not daylight runs on carrier groups.
While it might be a nice novelty for someone wanting to spend long hours patrolling for carrier groups so they can report them, the PBY is down the list in terms of use in AH in my opinion. Lots of other birds that would make more sense first.
