At 60 days out from Election Day, it's not just mail-in voting that's at risk. If all of those ballots have to be reprinted to remove his name, that's going to be a nightmare to get them all re-ordered and reproofed in time for Election Day.
On the other hand, maybe that's the plan. What if the court orders something that the printers and the registrars of voters are simply logistically incapable of accomplishing? Has that ever happened before?
