Is this possible doing by a plug-in?

Hello,

I'd like to develop a plug-in that would change the visualization of the score, to be more intuitive to a piano player, and also have a uniform vertical distance between notes, i.e. the vertical distance between a major interval would be greater than a minor interval, as in a piano.

Basically, the plug-in would do 5 things to the notes visualization:

1.Eliminate sharps and flats symbols
2.The sharp or flat notes would be slightly be moved up or down, to symbolize its accident.
3.All the notes without accidents would turn to a white note-head, like a piano white key.
4.All the slightly moved up and down notes would have a black note-head, like a piano black key.
5.Since the white/black half-note would be identical to a white/black quarter-note, the half-note head would be a square instead of a circle.

And one thing to the score visualization:

1.The E and G score lines would be nearer, since there are only a minor third between then, as also the D and F score lines.

This kind of visualization is possible doing in a plug-in?

Thank you,
Robson
