How Dutch battlecruisers change the Java campaign

How would three proposed Dutch battlecruisers alter the Battle of the Java Sea?

They would strengthen Allied command and firepower enough that Japan would likely postpone battle until capital ships could support the invasion force.

Adding three proposed Dutch battlecruisers changes more than the Allied order of battle. Their formation would bring a senior admiral and a proper staff, improving the coordination that historically failed in the Java campaign. Dutch radar-guided weapon development suggests the ships could also possess useful fire-control systems. Because Japanese heavy and light cruisers could not safely confront them, the battle would probably be delayed until Kongō-class or other capital ships arrived.
