That's a novel idea, but as long as there is a return water pipe, height is everything and volume means nothing. (while static at least)

OK, I have thought of a way to simplify explaining this.

Imagine a simple U shaped pipe with one arm twice the diameter as the other. The water would still settle evenly in both, regardless of water volume.

But potentially it could be easier to lift the water up the thin tube than the thick one. This is making my head hurt!!

Too be honest, with the amount of air and water flow available, I wouldn't really worry about res design at all.
