Invite Barcelona FC into the Scottish Football League - Soccer Idea

I know this is a controversial subject. But Catalonia keeps having controversial debates on whether it should not be part of Spain. 

Catalonia has a population of 7.5 million. But it also has one of the biggest football sides in the world, in FC Barcelona. A great team, with a great history and great players. 

But if Catalonia leaves Spain. Will Barcelona still want to play in the Spanish League, or will they get chucked out? Would Barcelona want to play in a Catalonia League or an already established league? How about Scotland invites FC Barcelona to play in the Scottish League against top Scottish sides?

We could have Barcelona and Espanyol playing in the Scottish League. 

Perhaps Girona, and CE Europa could play in the Scottish Soccer League too.

Thanks for reading my pie the sky idea.
Good luck.
