wrt the two questions about the Courageouses, my first thought is that the cruiser fleet tonnage limits of First London would make it imperative the Courageouses be scrapped as soon as possible, as each Courageous scrapped would make tonnage available to build three new cruisers. On the other hand, by the time of First London, the Deutschland was building, and the Admiralty might think the Courageouses were the perfect thing to kill Deutschlands.
As for a no Courageouses at all scenario, Jackie had tried to have a third Renown class, probably as Resistance, built, but his request was refused. The turrets were in hand, from the cancelled R-class ships. They probably would have ended up on monitors, or used on Hood, instead of the Mk II turrets being built from scratch. Regarding the impact on naval aviation, the Washington treaty does allow conversion of two ships that would otherwise be scrapped to be converted. The Wiki article on the G3s says there is no photographic evidence any of them were actually laid down. The G3s were so huge that they could probably not be cut down enough to get under the 33,000 limit anyway. The Lions were scheduled to be scrapped for treaty compliance. They are significantly shorter, and a bit beamier, than the Courageouses. Fit a modern, oil fired, plant, and their speed might be improved significantly. But the cost would probably be so great that the Admiralty would probably be better off building a clean sheet design. Without the Corageouses, something like Ark Royal would probably have been built in the late 20s.
