What teams would you put in the Euro Super League (Ie, replacing England or Italy with all the best teams in the world.

Thanks to the .edt file function you could start a game with 100 of the best teams in one set of leagues ;)

That's a nice option.

I heard that all new players (i.e. future created players) created for teams you swap end up being from the one league. So if you swapped in the best teams into the EPL, all new created youth players fro say Juventus (if you put them in the league) would become English. Kind of a downer.

Just create this league in a "low" country such as Andorra or Luxembourg. This would make an extra powerhouse world cup team !
