Social Security's Office of Inspector General (OIG) has done a report on Social Security's efforts to review Administrative Law Judge (ALJ) decisions. The report makes it clear that it is impossible for Social Security to target individual ALJs for review. The Administrative Procedure Act (APA) would have to be changed before Social Security could do that.
The APA is one of the proudest achievements of American legal thinking. Amending it to allow targeting of ALJs isn't going to happen. The APA is fundamental to American government. Neither Republicans nor Democrats have any interest in touching the APA.
