I had a few of these thoughts about the same thing you are probably thinking about. Like if i thinking what you are thinking than you were planning to attach the 40 amp grounds to the atc fuse panel since you had extra grounding room. In real life yes but this is FIRST and they are strict with their rules. Play the game safe and try not to anger the judges.
Here is a question now what if you only used the 12 slot atc fuse panel would you need the distribution block?
