There is no way in hell I could do it, oh wait, I have ovaries, that is a truer statement than I thought. But if you are going to do it....get appointed, and at your first service meeting talk, start giving a talk about the holy spirit and how it influences the headship principal in every congregation, that Jehovah's spirit guides the elders in making decisions, before you land the punchline. That its all a crock of BS. Sure, the elders might look at you at first, thinking this isn't the right talk, wtf? But until you land the plane, they won't know what's up
But keep in mind, you said you are still "in" for your family, becoming an elder and then dissing the org is a one way ticket to shunville, ASAP. So, how are you going to marry the two objectives you have going on? Screw the watchtower over and save your family relationship? Something to consider, seriously.
