Highly unlikely. Remember Scotland already has a separate legal system and different bank notes from England & Wales. The only way things could change massively would be if a newly independent Scotland left the EU, which as far as I know, noone wants. Scotland in the EU would mean Scotland would have access to the EU single market (which includes England etc.). This means there'd be no customs, visas etc with England (etc.)
