An ABDA fleet with ships, staff, and communications

What might an 'ABDA with teeth' have looked like if Force Z and a carrier survived?

It could combine Force Z, carriers, cruisers, and escorts under a British-led multinational staff able to make communications and operating procedures work.

The answer imagines Force Z surviving with a carrier and then becoming the core around which additional Allied cruisers and escorts could assemble. Prince of Wales, Repulse, carrier air power, and ABDA ships would make Japan confront a major fleet rather than scattered local forces. Hardware alone would not solve the coalition's problems. A British admiral aboard a suitable flagship could host a staff drawn from the participating navies and standardize reporting, signals, and operational procedures. The historical ABDA organization lacked that command space and preparation time, making coalition coordination a combat capability in its own right.
