Royal Navy capital ships replace the Pearl Harbor battle line

Exchanging British capital ships for the American battle line at Pearl Harbor would reduce the Royal Navy's speed and weaken its options against Germany and Italy.

Question

What if Royal Navy capital ships were exchanged with the battleships at Pearl Harbor just before the attack?

Short answer

Britain would lose important fast and modern capital ships and receive a generally slower battle line, worsening its existing mobility problem.

Notes

Assuming the exchange also changes ownership, Britain would receive a slower battle line and face greater difficulty matching German and Italian movements. Losing Renown, Repulse, King George V, and Prince of Wales would remove especially useful ships, while Nelson and Rodney would also be difficult to replace. The modernized Queen Elizabeth-class ships would be another substantial loss. American standard battleships capable of 21 knots would offer a small speed improvement over some poorly maintained Revenge-class ships. Colorado-class firepower would remain useful when positioned effectively, but those limited advantages would not compensate for the wider loss of capability.
