Oracle,
I recently "stepped aside" after being an elder for around 10 years and a MS for almost the same length. Born and raised in. Groomed from infancy to do things the WTS way. I was pretty gung-ho until I realized that several policies and doctrines (1914 being the chief doctrine) were unscriptural and in some cases, downright dangerous (policy on child abuse and the blood policy for two examples). I had thoughts of reform as well and if this request had been floated about a year ago, I would have jumped on the bandwagon. The main block to reform that I can see is the fact that the organization is so top down driven.
I'm not sure what type of reform you're hoping to achieve, but maybe laying a high level overview out would generate some interest. Minor things may change, mainly due to threat of legal action, but any large scale reform (again, not sure if you're looking for doctrinal reform of some sort or policy reform) is probably impossible. Remember that Franz tried to get the GB to change some things (at least according to him) and you see where that got him. If the GB wouldn't listen to one of their own, I'm not sure they would listen to any of their field hands.
I appauld your attempts but my belief is that even if you were able to get several high level Bethelites, COs and even numerous elders to put pressure on the org to make changes, the results would be their being DF'ed. Remember, they purged some pretty high ranking Bethelites before in the early 1980s and they wouldn't think twice about doing it again.
I'm interested in hearing your plan. I realize that since I'm not in the position you are looking for, there is probably very little I could do to assist, but you never know. I still have lots of folks I'm friendly with that are elders and they all think I stepped down because I needed to spend more time with my young family (which is mostly true). If you don't want to post it, maybe you can PM me with it?
