I'd like to offer some practical advice. Listen to your attorney. Wait to see what the Appeal's Council decides. At the point you are looking at a Federal lawsuit, than drastic majors like pursuing a lawsuit against an ALJ would be more appropriate, because if you think getting a fully favorable decision is a battle, getting an ALJ removed would be much more difficult. Get your approval and than you could try and bring attention to the problem of ALJs with so few approvals.

It took me many years to get my FF decision. Some of the delays were inexcusably SS's fault. (They lost the paperwork for my appeal for example.) But, in retrospect, most of the delays were caused by me, for a variety of reasons. You truly need overwhelming evidence in a scenario like yours, and that was what I realized, I had a mountain of medical records, but I needed to have my docs address what SS felt was vital, not what I logically thought was needed.
