I have a 5 gallon ATO on mine, and my sump is on the smaller size. If be more concerned with a overflow in the sump first.If you’re specifically worried about ATO could you simply make sure that the volume held in your ATO is small enough that even if the ATO pump or sensor failed that emptying your entire reservoir wouldn’t disrupt your tank?
For example I have a 120G tank and I fill my ATO around 3-4G. So “worst case” it’s like a 3% change in water. Guessing my parameters would barely move.
For AWC what’s the concern? Aren’t you just swapping “old” for “new”?
