Threats of legal action against the Elders involved but not the WT, may cause the Elders to back off.
When threatened, the Elders will then contact WT legal who should advise them that WT will likely not provide legal representation if the WT is not named. The Elders will be on their own and will will need to defend themselves if an action commences. That may cause some of the Elders to realize that in following the policies and procedures dictated by the WT, could effect their personal reputations in the community and possibly professionally, and negatively impact their familly bank accounts. Much added stress and worry including that by their wives.

Though you say Df'g maybe a relief, you are allowing them control over your fate. Although either option is playing by their rules, a better option maybe to resign instead: You can't fire me - I quit!
