Razer Blackwidow Elite PBT Keycaps upgrade for Azerty keyboards.

Hey all, I got a Blackwidow Elite Azerty and I would like to change my ABS keycaps. I dont mind switching to Qwerty so my question is the following, can I buy a PBT keycaps upgrade and substitute every azerty keys by the UK Iso layout? In other words, does the ISO Azerty layout and the ISO Uk layout share the same hardware keyboard or is it minor changes between iso azerty and UK? Thanks a lot for your feedback.
