Britain's large armored cruisers became battlecruisers

What might Britain build if it pursued large armored cruisers?

Before the First World War the answer is essentially the Invincible-class battlecruiser; a postwar design would require a separate scenario.

The panel first asks when the hypothetical design is meant to appear because the answer changes across the First World War. Before the war, Britain did build very large armored cruisers, but called the resulting Invincible class battlecruisers. That lineage points readers toward the Tiger-class discussion for later development of the same design logic. A postwar large armored cruiser is left open because the strategic and treaty context would require a separate design exercise.
