What if the British built ships similar to the Japanese Amagi design of 1921?

I have a photo on my cubical wall of the three-funnel British ship with five twin turrets with large guns:

What if the British built ships like this that were similar to the Japanese 8-8 program ships, such as the Amagi class? This ship design could have 10-16in guns and a speed of 30 knots without much problem. The dimensions would be 814ft x 104ft x 29ft. The secondary armament would be 14-6in QF guns. The belt would be 12in and the deck would be 4in. I will do a Springsharp design, later in the day, to test the idea.
