I’m willing to make a new font for this purpose. And if someone wants to submit some cool raster based files, I’d be willing to vectorize (trace) them. I would be doing this in Adobe Illustrator. Compared to AI, I don’t think cloud based solutions are very reliable for tracing. (You’ll get plenty of ‘holes’ filled with white.)
The question still remains how to more predictably randomize (in code) a range of characters/glyphs for an existing font. We’re discussing that here: Using/Changing Fonts used in ETC Modes
