they are actually pretty good with that sort of thing.
The worst they can say is no.
So I would get all your data together and send it to them.
Alot of it is arse covering and if they have someone of note that has put there name to the fact that they say you are good to go they may go for it.
I would try and do it before EASA. The CAA medical are pretty good actually and really do try and keep pilots flying.
