I don't understand what C, below and above mean. Making the bass and treble clef notes the same seems like a win. Other than that the traditional notes seem pretty easy to read.
There's also the fact that Treble (G) Clef and Bass (F) Clef are a perfect fifth away from Middle C, which reinforces the importance of perfect fifths in the system of major keys, but I suppose that's a small consideration overall.
above: a below: b
