Half the trouble is that for those of us with the Airbus laptop performance device (LPC), we can only perform calculations for airports on our network; it does not give us the facility to do the sums that you ask and there simply aren't any airports even close to that elevation in Europe that could accommodate the A320.
Having said that, I too am pretty sure that the answer is no!! Eg typical app/climb gradient at or around MLW in temperate climate with around 1000' pressure alt is 5%.
