I would also be asking why you need a wholesale change in by-laws right now. I suspect (hope) that one of the forthcoming changes to strata law may be to ban proxy harvesting. Maybe somebody trying to push through changes before the shutter comes down on a system that turns democracies into dictatorships.
In practical terms I’d focus on the 25 percent of people you need to block the changes and ask them if they really think you need to rewrite the rule book now when you are probably going to have to tweak them, at the very least, by this time next year, if not before.
