Aircraft types on 1/9/39 assuming the D Class carriers prompted more investment in Naval Aviation.
Fighters
Sea Gladiators being fazed out in favour of Gloster built Sea Hurricanes (with folding wings)
Scout/Dive Bombers
Skua with Fulmar in final stages of development
Torpedo Bomber
Fairey Swordfish and Albacore
Communications
Supermarine Walrus
I strongly suggest you drop the
Albacore.
Even the OTL RN knew the Albacore was not good enough, they issued a requirement for it's replacement before the first prototype flew. (That was the Requirement S.24/37 that eventually lead to the Fairey Barracuda)
If you decide the RN would benefit from a better biplane TSR simply ask Fairey for an improved Mark of the Swordfish. OTL they were able to fit a closed cockpit and ought to have improved the engine. IIRC the original Swordfish had an engine upgrade even before it was accepted.
Use the time, money and brainpower saved to bring forward the first monoplane TSR
perhaps even taking the route of a design like the Supermarine 322 which had the attraction of using less strategic material.
If started earlier then like your TTL Fulmar it would also be in "final stages of development" in 1939
