If Norway had fought Cossack over Altmark

What might have happened if Norwegian forces had resisted Cossack during the Altmark incident?

The clash could have produced an early British intervention or port concessions, because discovery of the prisoners would have weakened Norway's political case and Germany was not yet ready to move quickly.

An armed clash would have placed Norway in an even more dangerous political position once British sailors found the prisoners. The Norwegian public was broadly pro-Allied, while the government had already failed to establish Altmark's true status. Britain could mobilize for a Norwegian operation faster than Germany was then ready to respond and might have demanded occupation rights at ports such as Narvik. The crisis could have led to heavily armed neutrality, forced concessions, or an early Allied foothold rather than a simple Norwegian turn toward Germany.
