Could Britain have concentrated more capital ships in the Eastern Fleet?

Could the Royal Navy have reduced Atlantic commitments and sent most capital ships to the Eastern Fleet?

Not realistically, but it could have concentrated the Far Eastern battleships, Force Z, and Hermes into a more credible combined force.

The Mediterranean was the largest competing demand for Royal Navy capital ships, while others had to contain the German ships threatening Atlantic traffic. Sending most of the battle fleet east was therefore unrealistic. The proposed alternative concentrates four Revenge-class battleships with Prince of Wales, Repulse, and Hermes. Even a small carrier could contribute fighters and scouting aircraft to that combined force. Six capital ships and a carrier in the Indian Ocean would look more dangerous than two fast capital ships pushed forward to Singapore. The criticism is that British political leaders underestimated Japan and overestimated the deterrent effect of those two ships. A larger concentration would oblige Japan to consider committing more ships to defeat it.
