I think they might find they have bitten off more than they can chew.
It is much like the bluster of the wee red headed krankie......she was going to get a special deal with the EU to allow Scotland to stay in. She got told where to go.....and she was told in no uncertain terms that if Scotland did at some point gain independence, they would have to go through the formal application to join the EU.
This would involve a very lengthy process( Turkey has been trying to gain access since sometime in the 80's) and as part of the conditions they would have to accept the Euro as their currency.
