They don't even need to do that. They can just insert a thumb drive and upload a fake database of ballots as if they were scanned, without ever scanning a single ballot, or scan real ballots as normal then upload from a thumb drive to replace the ballot database with a fake one made months ago. Then after the election is over, they erase everything and go into the physical ballot storage and switch hand made fraud ballots in for the next week after the election, so even a recount wouldn't show anything.
