Aha, I finally figured this out!!! I had been stuck on this issue for years, LOL! The key is to redefine the codePoint of smufl.glyph.alteration.prefix.flatsmall and smufl.glyph.alteration.prefix.sharpsmall, then fix the positioning in all the composites that use those glyphs.
With no overrides at all in my file, and with my doricolib files active, here’s what I get at 76%:
With my new Chord Symbol Small Suffix Accidentals doricolib file active, I now get this at 70% where the sharps and flats match the same glyphs as they do at 76%:
Here's the code

You may need to tweak the positioning to work with your default fonts, but that’s easy to do. Negative yOffset values are up and positive values down. Once you’ve installed the doricolib in your DefaultLibraryAdditions folder, then any file started from File / New will automatically contain the modifications. You can bring them into existing files with the Library Manager.
