I was never an elder so I could be wrong, but something tells me that the typical BOE might not look so kindly upon you reporting this "exemplary" MS. You, are DFed (and are not to be mourned and are to be viewed as having been killed by Jehovah, according to a recent WT study) and you're a lowly weaker vessel. Making a choice between you and one of their own isn't going to be difficult for them. Once they decide that your information isn't worth acting on they'll then have to sort out a punishment for you for bringing it to them in the first place. It might not be a conscious decision to punish you for it, but given the paranoid nature of the cult I wouldn't be surprised if they "circle the wagons" and make sure you don't get reinstated because you now are seen as having a tendency to try to "cause divisions" or slander men in authority. You've absolutely got the deck stacked against you here.
Whether you move to a different congregation or not, I have no idea. Maybe someone who's an elder can give you some advice there as to whether there's any time penalty for getting reinstated in another congregation. If not, you'd probably have a better chance of getting reinstated if you can win over elders that don't know you and are starting fresh and get them to recommend you for reinstatement vs trying to win over elders that already have a bad opinion of you.
