Well, I think with the paper ballots to compare to the Dominion totals, you could discount (although not completely eliminate,) the idea that the machines themselves changed the count, regardless of the ballots.
However, you’d be assuming a transparent chain of custody. Wood complains that there were several hours where the ballots were unobserved after the polls closed but during the counting process, and that is where paper switching or even adding could have taken place. He has some convincing affidavits to that effect.
With all the down ballot stuff, I don't think it could be possible to shuffle out Trump ballots and replace with Biden ballots and keep the totals the same as reported for each candidate for each race. You would have to have the ballots presorted or you would have to replace 100% of the ballots. At some point you just have to give up on the idea.
There is a lot more potential in the "valid" vs. "invalid" ballot arguments. Let's check the signatures. The one depressing thing in Georgia though is that absentee ballots were only mailed out by request, so it isn't like there were ballots flooding the streets like in some states.
Here is something that is interesting though. Before the June primary Georgia sent an application for absentee ballot to ALL voters. In the General election, they did not do this. As I understand it, the SoS did not mail the applications because of pressure from the GOP. We might have shot ourselves in the foot on that one.
