From the little knowledge I have in network engineering, I believe you should be able to divide the physical resources and bandwidth of the mega-servers however you like. In a way it should be similar to the cloud servers I manage for my games (minecraft and more).
How about, in that case, starting a completely separate clean server with most of the fixes (like the duping fix) already applied from its start, seeing how many people will register for it at the start, dividing the resources according to them and allowing them to populate it? Nothing will ever be completely bug-free but at least ensuring it's free of game-breaking and criticals bugs or dupes.
The original server is not affected in any way while people who prefer a completely clean experience have a chance to start anew.
