I'm sorry to see that no one has got any information for you, but I think it's rather a difficult situation, and many pilots will know how difficult is it to simply refuse to comply with an airlines 'rules'.
They have always taken the attitude that 'We pay, so you'll do what we say.' So often, it is blatantly unfair, or even unsafe.
I would think your only hope is to have the AMEs protest this themselves. After all, it's against their interests. I'd imagine that if a few of them knew the problem, they would be motivated to circulate the news to their colleagues. Perhaps this could be done via some central office or a medical publication that would convey it to the attention off the more distant doctors.
