Which British admiral could take Kimmel's command?

Which Royal Navy admiral would have been given Kimmel's command in a roster swap?

Probably James Somerville, with Andrew Cunningham imagined as finding a way to avoid the poisoned chalice.

A speculative roster swap replaces the American senior command with Royal Navy admirals. James Somerville receives the Pacific Fleet, with a joke that Andrew Cunningham would have managed to avoid the appointment. This is a terse counterfactual judgment rather than a claim about an actual selection process. Its value lies in comparing the command burden at Hawaii with the British officers thought able to endure a difficult, under-resourced theater.
