I would suggest you fly to any second-tier city in the Nordics e.g. LHR to Stavanger or Gothenberg, Trondheim, Lulea or whereever you like to go. On a SAS Plus Pro ticket you should be able to collect 2050 points for each leg, + 25% extra as Gold member you should make 5125 points per round-trip. Adding the promotion (x2 status points) makes 10250 points and you should maintain EDB. The return trip costs you around 400 € in the cheapest travel class (A).
