Prince of Wales and Repulse as ABDA's command core

What if Prince of Wales and Repulse survived and were available to ABDA Command?

Their presence could draw more Eastern Fleet units forward and give Admiral Phillips a flagship large enough to coordinate British, Dutch, American, and Australian staffs.

Prince of Wales offers enough staff space for a multinational headquarters. Phillips could bring British, Dutch, American, and Australian liaison officers together aboard one flagship. That arrangement would give ABDA's disparate navies a stronger centre for planning and coordination. The survival of both capital ships could also encourage reinforcements intended for the Eastern Fleet to move forward sooner.
