Yes, it's something I've been thinking of. The Blackburn Skua needed replacing, the Carriers needed multi-role aircraft the FAA didn't like single-seaters; so a navalised Henley with wing guns ( a mk ll would have two 20mm guns), would make an excellent fighter/dive-bomber. It would have been as good as the Fulmar as a fighter, and more flexible.
Coming into service in mid 1940 it would've made an impact in the Norway campaign, and what a difference it would have made to Taranto, and the Battle of Cape Matopan!
Whether later it would have been re-engined and enlarged, or at least made the Barracuda better by having a Griffon engine, when it replaced it!
