How a surviving Force Z could change Allied concentration

If Force Z survived its first air attack, how might the Allied fleet in Southeast Asia develop?

It could form the core of a larger Allied fleet, with later carrier and battleship reinforcements forcing Japan to commit more naval power.

A surviving Force Z could become the nucleus of a larger Allied fleet in Southeast Asia. Two fast capital ships and two British carriers, with Saratoga and other American assets potentially joining later, would require a larger Japanese response. Japan's main carrier force would first need to return home to rearm, refuel, and repair. By the time of its later Indian Ocean operations, Indomitable, Illustrious, Warspite, and other Eastern Fleet assets could have joined the surviving force. This is a conditional sequence of reinforcements whose outcome depends on the extra time bought by surviving the first attack.
