If you think it, makes sense to arm the ships with the 9.2 in because is sufficient to make important damage to a pocket battleship or even a proper battleship, not that they run into them but if necessary to make a stand by a squadron or two.
Would the Leanders count as "prime builds"? They seem to have been well built, since at least one (HMS Achilles / INS Delhi) lasted over 40 years in service. They also seem to be smaller, less capable ships intended to provide numbers. Maybe they are the exception that proves the rule, or maybe not?
Why didn't the RN actually build any heavy cruisers after 1931? Even once the treaty limits were gone they chose to build light cruisers. Presumably some of the later Town or Colony class could have been larger 8" ships?
I know they designed some, but I am curious why they didn't seem to build any more heavy cruisers in OTL. The US in its wartime programs built both 6" and 8" cruisers (yes, probably just because it could). Did an 8" cruiser take that much longer to build, or was it just that there didn't seem to be the need in the RN for more 8" cruisers?
For that matter, the British built about 251,000 tons of cruisers between 1918 and 1935 in OTL, not counting the wartime designs like the D and later C class cruisers. I am counting the Emeralds, the Leanders, the Hawkins, the Kents, the Londons, the Norfolks, and the Yorks (27 total ships). Assuming the British could afford (ITTL due to the better postwar economy) to build another 75,000 tons of cruisers up to 15,000 tons with 9.2" guns, would they just build five such cruisers or would they build 2-3 and more smaller cruisers?

Ah, and could someone please give me the rundown on the alternate classes the Brits have built here? Class name, # of ships, and basic wikibox stats, please.

I can't say - that's for @sts-200 to write. I would say that 2-3 cruisers of an individual type would be unlikely as they (allowing for refit, maintenance, etc as you've pointed out) would be "odd ships out" and unable to form a unit come wartime. 5 is a possibility, but a "pre-War" mentality RN would want at least 8 I'd imagine.
I'd say a cruiser squadron of 1-2 of the proposed CA's and 3-4 of the proposed CL's would be a good compromise-more ships to cover space, the CL's can run to the CA's if needed or shadow their quarry an guide the CA's in
Fair enough, but I am curious about what a less constrained RN might have chosen to build.

Well if the British have any say the limit won't be 8" - took them best part of a decade to get a satisfactorily working gun
The only thing I would say is the 8” designed for the RN OTL was very much a “treaty design” and had a troubled service life for its first few years.
Most of the problems seem to have been satisfactorily resolved prior to the start of World War II, but HMS London reported as late as June 1938 that "one would wish that the 8in mountings and torpedoes would behave as they should. The prolonged firing of 20 rounds per gun from London was a disappointment on the material side." (NavWeaps)
I believe that given the choice, the RN would carry on with the already in service 9.2” and develop a new gun based on this “trusted” calibre. The 7.5” was designed pre-War so a “trade cruiser” designed to defeat enemy 6” cruisers is a possibility.
Elevation | Mark I, I* and II: -3 / +70 degrees Mark II*: -3 / +50 degrees |

Was it the 8" gun that was the problem, or the mountings? According to NavWeaps the designers tried to give the British 8" twin mount Mk I and II a 70 degree max elevation for AA use, despite the fact that the rate of fire and traverse speed was grossly inadequate for AA use. The gun itself seems to have been a serviceable weapon.
The US twin and triple 8" on the US treaty cruisers only had 41 degrees of elevation and seems to have worked better.
Good news for Armistice Day commemorations in the future ITTL - less need for thermals on parade.on Sunday, 30th September 1917, <snip> At midday, the guns fell silent
Alright, so the Brits have:A summary from some way back, which is still relevant to the current state of the story (except Glorious is a wreck in the Scheldt):
'State of the Fleets, May 1917'

OTL Britain determined they needed 70 cruisers at minimum, 45 on the trade routes and 25 as fleet cruisers for working with the destroyers. As in OTL, the British have a mess of C and D-class cruisers either built or under construction that can do the fleet work, so the priority is going to be those 45 trade protection ships, especially since the newest ships that can do it are the 25-knot, coal-fired Towns. I'd need to crack open my books to get the specific ship mix, though, and can't do that ATM.One solution would be eight 15,000 to 9.2" cruisers, seven 10,000 ton 8" cruisers, and 18 7,500 ton 6" cruisers for 33 cruisers at 325,000 tons. Another would be eight 15,000 ton and twenty-seven 7,500 to cruisers for 35 cruisers at 322,500 tons. I think this later (8 big CAs, 27 CLs) may be a better mix, but should there be other designs? If they just wanted big cruisers, they could get 22 of the 9.2" ships for 330,000 tons.
In OTL, the British built something like 65 light cruisers for WW1, with no armored cruisers and only the Hawkins class as heavier cruisers. I expect they don't need quite that many post war because aircraft will pick up a fair amount of the scouting role of Grand Fleets cruiser squadrons, but they will need some. Maybe the mix suggested by CV(N)-6 would work?
