Your mission should you chose to except it is to give Sweden a colonial empire with a POD after 1816 .It does not have to be large ,just a few islands in the Pacific or Caribbean and/or African holdings the size of Spanish Sahara .Then you have to turn Sweden into a naval power on par with any of the south American nations were in the early 1890`s .The navy must have at least a squadron of BB`s and enough smaller vessels to protect the nations holdings from any hostile power (Russia ,Germany ,Denmark ,UK and others ) .Double points if you can continue the scenario past WWII or even butterfly away the war .
