note name notation?

Hi,
im wondering if a notation could be arrived at, similar to the example , attached.
Its based on they way Cecil Taylor presented his material to us when I worked with him (though Cecil usually wouldnt notate rhythm; we learned the phrasing in rehearsals).

It has some advantages, particularly when material has to be adaptable to different ensemble configurations, for example:
A) clefs arent needed;
B) the lines within complex chord movements can be assigned to various players as the ensemble changes.

while I can write this out by hand, it would be useful to have it in Musescore for instrument transposition.

i ve already read the thread on notating unmetered music, so thats not a problem.

the question is how to replace the note heads. There is under Master Palette - > Symbols, a palette for "Note Name Noteheads," which is similar, but it operates as symbols that you add in addition to note insertion, it doesnt replace the note head itself. Ideally I'd like the actual notehead to disappear and just see the letter .

also, would there be a way to suppress the actual stave lines?

thanks,
Mustafa
