Venezia-class cruisers strain Italy's fuel and British planning

What if every Italian cruiser became a World of Warships Venezia-class heavy cruiser in 1940?

Italy gains roughly twenty powerful cruisers that severely complicate British planning, but fuel limits their sorties and the preferred balance with battleships remains disputed.

Replacing every Italian cruiser with the fictional World of Warships Venezia would produce roughly twenty ships armed with fifteen eight-inch guns apiece, assuming the game-derived radar fit works as described. Fuel remains scarce, but the greater fighting power and uniform cruiser fleet lead to disagreement over whether losing the smaller ships is a serious disadvantage. Even one or two Venezias would demand a stronger British response than ordinary treaty cruisers could provide. U-class submarines and a Taranto-style air attack become important ways to strike them before they can fight at sea. British construction priorities would favour getting fast capital ships into service quickly, because a new cruiser design would take time. There is also disagreement over whether Italy should spend scarce fuel on several Venezias or on Littorio-class battleships against British capital ships. The hypothetical creates a major operational problem for Britain without resolving Italian fuel shortages or establishing a decisive outcome.
