Could Canadian Renowns produce a 28-knot Admiral fast battleship?

Would four additional Canadian Renown-class ships make Britain complete the Admirals as fast battleships?

Possibly. The suggested alternative trades battlecruiser speed for a wider hull, better protection and subdivision, producing roughly 45,000-ton ships with twelve 15-inch guns and about 28 knots.

Additional Renowns would strengthen the argument that Britain already had enough battlecruisers and should build fast battleships instead. The suggested Admirals use a wider, somewhat shorter hull with more armor and subdivision. Triple turrets would provide twelve 15-inch guns on about 45,000 tons while using infrastructure capable of building Hood. More subdivision reduces the space available for boilers, while the changed hull form also costs speed, leading to the proposed 28 knots. The better-protected design might avoid the same post-Jutland interruption and allow all four ships to be completed. The resulting British and Canadian force would change the capital-ship balance facing Washington treaty negotiators.
