Sacred Harp, Shaped Notes

Here in the Southern U. S. we have a need for Shaped notes. here is a link to explain.

The Shaped notes are available in musescore. (note properties-->note head group -->do, ra, me, fa, la, ti (so is normal))

It appears to me that the Color Notes plugin could be used to create a Shaped note Plugin with a little modification.

This is beyond my limited programing talent.

What is your thoughts.
