You could do some pretty serious testing if you had the actual ballots to be used for the election. But as you say, the options could be changed afterward. Unless there are already live election results, you can change anything you want before the election except the printed ballots.

And early voting is a separate election entirely as far as I know.

The problem with getting these recounts is that no one wants to do or approve them unless it can change the outcome. For President, this is hard. Ohio or FL alone could do it, but even IA and NM together wouldn't be enough. The danger is that you don't improve the system or learn from your mistakes if you can't discover them.
