Fast forward 20 years and the three remaining ships are surveyed as to their future use. The ships had spent their wars in the Pacific and had not had the hard usage that the Light cruisers that had gone to the Grand Fleet had. Why only three left? While cruising through the Marshal Islands one encountered a typhoon that blew the ship onto a reef that wrecked it. The threat from Japan had increased markedly in 1930-31 when they failed to sign the current Treaty to limit ship sizes and numbers. After that every hull that could be used for up to ten years was reprieved from the scrap heap and put into some form of useful service to the Empire.
The next thing is to figure out how far I should take any refits, rebuilding, of these ships. What form of service could be expected of these old cruisers. What I would envisage these cruisers to be useful for is as Patrol and Escort cruisers. The main portion of that usage would be a catapult and aircraft handling facilities. This would entail the removal of five of the aft 4" and the torpedoes. A set of boilers would be removed and the rest converted from coal firing to oil fired.
A 24 knot speed was ample for all of the designated roles envisaged for the three ships. Out on the Trade routes or as escorts to the convoys, they would be useful and allow front line units to keep with the fleet.
