Fuji, none of us here (so far as I know) are involved with the BGA other than as members through our clubs. None of us are on any committees they have, none of us can comment one what dialogues they might or might not be having with EASA.
We are commenting on what we can - the status quo.
So please stop making assumptions about what discussions the BGA might (or might not) be involved in with the EASA.
And, none of us have any intention of risking any insurance claim by being non-compliant with the rules as they are at present. I can imagine the howls of anguish from you if you had a claim against someone who turned out to be uninsured through making the sort of unapproved change you are suggesting many of us do. We wouldn't hear the last of it.
