A Renown-derived alternative to Courageous, Glorious, and Furious

What might Courageous, Glorious, and Furious have looked like if they followed the path toward the Admiral class?

They could have resembled enlarged Renowns with three triple 15-inch turrets, creating a nine-gun evolutionary design.

This counterfactual sends Courageous, Glorious, and Furious down the existing Renown design path rather than into their historical large light cruiser forms. The alternative would be a 30,000-ton-plus battlecruiser built around three triple 15-inch turrets. Nine guns in three mountings would preserve a powerful broadside while evolving a proven fast-capital-ship hull. Applied to Hood, four triple mountings would produce a twelve-gun ship. That heavier battery would require more power to maintain speed.
