JANKO musical Kbd notation correction template

[jjj]

Greeting to all you gifted designers,

To adapt one innovative notation to another (which I created) I need to create a template. Instead of bombarding you busy, good people with 1000 boring details, here I depict what I need. Here You see one octave of (Before) Klavarskribo notation, which I need to change to the "After" design to fit the 3-row Janko/ Uniform keyboard layout:


Since most graphic designers are rarely musicians as well, the above drawings should be neutral and simple for all to understand.
Q: Which software is best suited for this task? I have no graphic skills, but as a young pensioner (70) from East Germany, I'm already used to all sorts of "hard lives"!
Ideal would be a transparent type of template, which I drop onto a picture of the original (Klavarskribo) notation, to correct the lines.
Besides, I'm, a "whistler-musician". (Watch me blowing up on YouTube: EW8KdBxds) Chances are, you don't like my (mother's designed) face, but at least might like what you hear!
In case you too are musically spirited, I can enlighten you with the details of my project. Basically, I built my own wooden Janko Kbd and created an innovative WYSIWYG Klavarskribo type notation for a 3-row Janko/ Uniform Kbd layout for my Tyros3.
