Could Admiral Byng have improved the command?

Could putting Admiral Byng in charge have improved the Cartagena expedition?

Probably in this counterfactual: a full admiral could establish one recognized commander, and Byng is credited with useful organizational ability.

The suggestion that Admiral Byng might have improved the expedition rests on an assumed full admiral's authority. In that scenario, one officer would hold overall command instead of leaving rivals to negotiate through a council. Byng is also credited with useful organizational ability. The claim is a counterfactual about clear authority, not evidence that a different commander would automatically overcome the missing engineers and siege support.
