Swedes are the most conservative on doing anything new to their sports. No merning talks between the league officials, im pretty sure. If Swedish league finds a way to seperate even more from others, it will do it probably
But it does make sense from fans point of view. The problem is, the HC fans of the teams in both countries are very traditionalist and probably not most intrested. Still, I think closed Nordic league with 12 clubs would be pretty gem. It would also leave pretty competitive second tier series for both countries own soil.
It would never happen, at least not from a Swedish perspective. Just the talk of giving two "wild cards" (direct promotion to SHL) to two clubs in the second division Hockeyallsvenskan, remove Kvalserien (most beautiful thing in hockey) and replace it with a playout+playoff made
everyone go against the SHL-board. SHL-fans even threatened to boycott the games!
Imagine if they would bring up the talk to close the league entirely, oh my God, God bless them that they'll get out alive
Edit: Hockeyallsvenskan would become as bad as Mestis is today with a closed league, no one wants that in Sweden. Right now, Hockeyallsvenskan is unofficially the best second division league in Europe, with a lot of media interest and TV-games. Even now when SHL has removed Kvalserien from next season, Hockeyallsvenskan will probably lose some interest and skills.
If they could still use the promotion/relegation system with one or two clubs from each country every season, people would probably be more open to that proposal in a Swedish point of view.
