A&C - Cats is right, there won't be anything like that sort of change to the airframe. Especially since the MoD/ACO/RAF don't even own the aircraft.
It would be more likely (in the current environment) that they would do a risk assessment, say that the canopy (in its present form) is too greater a risk to continue using in that role (AEF), and that the AEF should therefore be scrapped ('paused')
