Could German helicopter landings alter the Norwegian campaign?

Could German helicopters land troops ahead of the naval forces entering Norway?

They could contribute, but Germany would need dedicated aviation ships because its treaty destroyers lack the displacement and stability for useful helicopter groups.

German helicopters could add reconnaissance and troop movement to the Norwegian campaign, so the counterfactual is not an exclusively British advantage. German destroyers are poor helicopter platforms because they already carry heavy guns, torpedoes, and substantial top weight. Germany would need helicopter sloops or a dedicated carrier to bring useful numbers to Norway. Small landing parties also risk immediate fire from local troops or reservists rather than guaranteed surprise. British confidence in helicopter anti-submarine cover might meanwhile encourage a stronger forward naval posture along the Norwegian coast, potentially intercepting the German force earlier.
