If we assume an attempted surface-borne assault, this could have an interesting effect on the Norwegian Campaign. IOTL, thanks to poor ship recognition skills in Coastal Command, and a certain amount of bad luck, Admiral Forbes became convinced that the Germans were attempting to break raiders out into the North Atlantic, and pulled his forces into positions from which they could less effectively respond to the German invasion of Norway as a result. ITTL, if these intelligence failures continue (and there's no reason they shouldn't) then, since there are actually ships heading into the North Atlantic, Forbes will give chase to a greater extent. The forces heading to the Faroes/Iceland will be sunk, but the British response in Norway will be delayed; perhaps Narvik is less of a crushing victory for the RN than IOTL, and the Lofoten Action will be avoided.
