Four 15-inch battlecruisers at Jutland

If four better-armed Renowns had been ordered earlier, could they have reached Jutland and changed it?

Possibly: four extra 15-inch battlecruisers could badly damage the German battlecruisers, but the scenario depends on earlier construction across the British fleet.

Earlier Renowns form a consequential but demanding procurement counterfactual. Four additional 15-inch-gun battlecruisers could have made the run to the south far more punishing for the German scouting force. This outcome also presupposes earlier completion of other British capital ships and ammunition improvements.
