I wouldn't be trying to keep anything a secret from CTC or the CAA. Not the right way to go about it.
Also, CTC require that you link your CAA account with them so that they can check exam history and book exams etc.
If Route 4 is still going in a year's time, you could always do your CPL modular, and then apply to do the MCC/AQC with CTC and easyJet?
