Whilst heading south why don't you give Gerona a call and ask for overhead crossing and the use of corridor A? In my recent hourbuilding tour (24/6-5/7) over there (Balearic isles and Spanish mainland) i've found spanish air traffic control very helpfull & friendly, even with airborne requests regarding possible routeing, however if they cannot allow you to do so, have the plan B ready...
Regards and good luck!
