Have extra alliance members for larger regional or 2-4 more alliances.

An example of the first one is at regionals with 40-45 or less teams you would still have only 3 teams to an alliance. While at regionals with 45+ teams your would have 4 teams on an alliance. You would rotate in the extra robot after each match, just like it was right before we started having games with 6 teams on the field. You could augment it a little by only being able to play in 3 straight matches. This makes it so you aren't switching between only 2 robots and would make strategy important. You would allow the alliance captain to be in the player station for strategy during the matches there robot is not on the field. One problem with this is how many open slots are open for registering for the Championship event vs how many slots are set aside for regional champions. This is something that could be used at the Championship event.

The example of the second one is just what the do at GTR. You have more alliances and make a "wild card" round with the extra alliances. This one is harder to do at the Championship event, I think it would only make the day longer, and I think being there until 6:30-7:00, or later, at night is long enough.

These are good ideas for allowing more teams to be in the elimination matches and give them experience being there.

Note: I called it "Championship event" Because I didn't want to call it Nationals. It's not that any more because FIRST is global not just national.
