Roger Keyes and an early joint Pacific defence

What if Britain created a joint Pacific command under Roger Keyes in August 1940?

It would likely become more integrated and rely on forward flotillas, mines and submarines while keeping capital ships less exposed.

Keyes would have eighteen months to accelerate organization among British, Australian, Dutch, New Zealand and Canadian forces. Destroyers and other small combatants could reach regional navies sooner under that structure. Keyes's flotilla-defence thinking puts submarines, destroyers and minelayers forward while holding the battle fleet at a strategically ambiguous distance. That posture avoids concentrating capital ships where Japan can quickly locate and destroy them.
