Looking at that FTS started me thinking - which is sometimes hazardous! Your original ripariums were all designed around the aquarium being a "frame", a box that enclosed the scene being viewed. That made using the golden ratio a good way to set the ratio between the above water and below water portions, and led to the 40% full of water riparium.
Later, we tried reversing the golden ratio, with a 60% full (roughly) of water tank, which this is similar to. But, with a rimless tank, as this one is, there is no "frame" or "box" that contains what we see. And, the above water portion is small enough that there is little humidity benefit gained by having the plants down in the tank a bit. So, wouldn't a rimless tank, with water almost filling the tank, leaving just enough above water area for the planters to attach to, be the "best" layout? That really would make the top of the tank disappear from view, and it would allow the best development of the aquascape too, plus allowing the maximum room for fish.
One pitfall to avoid is using tanks with the plastic rims removed, so that we rely on excess glass above the water line to reinforce the glass and prevent too much bulging out. Maybe this arrangement has to be limited to tanks that are known to be strong enough, rimless, to handle a full tank of water without risk.
Do you have such a tank so you can be the guinea pig and set up one? This one would look even better that way I think, but I'm not sure the glass is strong enough.
