I like the idea of a chromatic staff. Making notes visually more evenly spaced would probably make certain things clearer, and probably would provide some interesting insights from a musical analysis point of view. The fact that it still uses the same 5-line staff would make it easier to adopt. It's familiar, and you can use existing staff paper.
However, speaking as a reasonably proficient sight reader, I don't know how much more improvement this adds. From a readability point of view, this looks about the same to me (which I suppose is half the point). Maybe I'm just a jaded musician, but I just don't find music notation that hard to pick up.
Reading music is very similar mental process to reading text. Your brain quickly learns to chunk notes into patterns rather than individual groups, similar to how in reading you don't actually parse out every single letter.
