What supporting cruisers could add at Denmark Strait

How might the Battle of the Denmark Strait change if British cruisers joined the action?

Their spotting, extra fire, and additional silhouettes could distract the German ships, help identify the correct target, and damage exposed fire-control systems even without penetrating battleship armor.

Supporting cruisers matter through more than their nominal shell weight. They add observers, targets, and a continuing volume of fire. County-class silhouettes might confuse German identification, while six- or eight-inch hits in the wrong place could disrupt fire control and help the British correct the historical Bismarck-Prinz Eugen target mix-up.
