If Prince of Wales had been lost with Hood

What would the Royal Navy do if Prince of Wales had been sunk with Hood?

It would accelerate capital-ship responses, likely question the 14-inch gun choice, and keep scarce battleships concentrated rather than send them to the Far East.

The double loss would trigger an immediate search for causes. The 14-inch armament would become a likely target of criticism, while the Lion programme might be accelerated or reshaped around larger guns. A simultaneous shortage of modern capital ships would also encourage the Royal Navy to concentrate them in groups. That pressure would make it much less likely that scarce battleships could be detached to the Far East.
