Astrodragon, except I'm not certain how wise attacks on Swedish shipping or in Swedish waters would be, especially after France falls.
What is still needed is for the Allies to actually deploy a credible fighting force to Norway, even after early victories intercepting the German forces headed for Narvik and Trondheim.
In all likelihood the Allies will need both to have a chance of winning and the odds still favor Germany.
As it was the Allies took much longer to deploy a much smaller force, despite a vast edge in naval and merchant shipping, than Germany did and that does not bode well for their behavior in an altered situation.
On the other hand, destroying 14 of Germany's 20 destroyers, the Admiral Hipper(hard luck ship of the Kriegsmarine) and perhaps the twins will put paid to any Sea Lion schemes. Which does raise the worrying question of what else Hitler will try...
Sorry, I wasnt suggesting that Britain did anything in Swedish waters, I was thnking outside of them. Having bases in southern Norway means you can get further into the Baltic with heavier loads of mines or torpedoes
Given that the KM was virtually destroyed as a fighting force anyway, additional sinkings wont make much difference (the ships are sunk rather than just damaged beyond immediate use). Despite the losses they suffered, the KM was actually lucky in the Norwegian campaign (aided, it must be admitted, by intelligence failures on the British part) - it would only take a bit less luck, or better weather early on, to turn it into the Death Ride of the KM...
