Walter Cowan would still go ashore at Narvik

If Walter Cowan commanded Warspite at Narvik, could he resist personally leading the landing force?

No; Cowan would probably go ashore, and Cossack being under Sherbrooke instead is jokingly called a saving grace for the Germans.

Cowan is treated as an officer unlikely to remain aboard while sailors fought ashore. Philip Vian provides a comparison for the same forward style. Command personality can change how a naval landing unfolds even when the ships and formal plan stay the same. Narvik becomes a compact example of individual temperament shaping an amphibious action.
