There's plenty of 'Automatic Water Changers' out there, Pacific sun maybe worth you looking at, although I don't know where they're upto now with regards to advancements. I know you used to be able to use their Kore 5th doser as an AWC if you sacrificed 2 channels so would hopefully do away with part of @ian_m concerns as the drain would exist as something an electronic device controlled and not be a direct drain in the sump.
As Ian correctly says you need to calculate the capacity of the sump and water that would drain from the aquarium should there be a power cut, this can make running a minimal rim to water level more of a challenge.
Possibly worth checking some of the marine forums out for some ideas.
I'll comment on your other thread RE: Water Flow.
