However, if I'm in Water change mode, I'm going to switch the relay and ATO port into a SingleATO, and then start up a drain pump for X seconds to fill a bucket. This should automate my water change routine. I'm going to re-use my reactor pump to redirect it's output to my drain bucket and get the benefit of automated and continuous water change and media rinsing

I can set the level of the float to just a bit over where my water level is when the skimmer and reactor are off. This way it doesn't trigger if doing other maintenance and then during water change, it'll be ready to start topping off as I drain, keeping the level just about the same.
The reason for putting them into parallel is because I'm getting the Avast Marine skimmate locker which has a ReefAngel connector to plug right into the ATO port. I will use this one to disable the skimmer if that gets full
