As for medical standards, the eyesight requirements for night and/or IMC work are beyond the remit of GPs, so the AME-adminstered part-Medical Class 2 must remain the minimum standard.
Does that mean that if
(1) I am currently "temporarily" medically unfit for a class 2
(2) I have a GP declaration
(3) I can thus fly with NPPL priviledges on my CAA SEP licence and class rating
that if I were pass the eyesight part of the class 2 medical[#] I might be able to persuade the CAA to let me use my IMC rating via some personal concession (assuming I complete the course and pass the test)?
[#] My AME is always happy with my eyesight, even though I fail the new standards, under grandfather rules (so I get a "NJC" rubber stamp) - with my glasses on I can see better than some of the people he has to pass under the new rules!
