Could studying Graf Spee revive a British heavy cruiser?

Could studying Graf Spee have led Britain to build 9.2-inch heavy cruisers?

Possibly, but mass-produced six-inch cruisers fitted contemporary needs better; earlier knowledge of battleship retirement would have strengthened the case for 9.2-inch ships.

The Royal Navy had genuine interest in 9.2-inch cruiser guns, so a close evaluation of Graf Spee could have influenced the debate. The obstacle was production strategy: Britain could build six-inch cruisers in quantity and believed groups of them could handle the likely cruiser threats. That made a new heavy-cruiser programme difficult to justify while battleships still provided the fleet's heavy gunfire. With foreknowledge of how quickly Britain would retire its battleships after the war, a 9.2-inch cruiser might instead have supplied a continuing core of heavy surface firepower.
