It might be against the rule, but here's the real question: Is it really going to matter?

Honestly, letting a team take a bot home AFTER THE SEASON IS OVER should be chill, because the game is over! If you're in a Tae Kwon Do tournament (west coast league, up near me...), they require you to ship your gear in a box, or leave it on their shipping zone the night before, so they can inspect it for cheating (no metal, etc). They're not gonna inspect it before letting you take it home, it's over. Same thing here, basically.
