I'm not quite clear on what you're suggesting. Remain canonically resident in the diocese, but have an outside association elsewhere more orthodox? To a degree that is done now -- but once the battle really gets going, look for that to be disallowed too.
Suppose an orthodox Episcopal parish wanted to secede from its non-orthodox diocese and affiliate with an orthodox bishop. Currently the non-orthodox diocese is likely to keep the parish property. But suppose the Anglican Communion classifies the orthodox parish as having "full status as a constituent church," and classifies the non-orthodox diocese as "in association without decision-making status." Could the parish then use this classification to argue in court that they are the legitimate owners of the parish property?
