How four G3s would reshape British battlecruiser squadrons

How would the Royal Navy organize its battlecruiser squadrons if all four G3s were completed?

The G3s would form the first squadron under a G3 flagship, with Hood leading the remaining battlecruisers in a second squadron.

The four G3s would operate together rather than being distributed one by one. One of the new ships would serve as flagship of the first battlecruiser squadron. Hood would then lead a second squadron built from the surviving older battlecruisers. A coherent class of modern ships could create a new tactical formation while displacing an existing flagship into a secondary group.
