As soon as you start next season without 3 promoted teams and 3 still there that should have been relegated, whoever that might have been, or those places having been decided by some voodoo, then next season, whether or not it can finish, is already compromised or 'asterixe' before it starts.
Voiding is not even a 'clean break' anyway, so why even consider it? Only makes senses in factional terms.
