Okay our job in this dir is a fun one. questions first though... I want to make a "stable
  diffusion" type font ligature set, where it intentionally corrupts the spelling of words by
  applying ligatures to groups of letters that Stable Diffusion 1.5 would generate. Like "The"
  becomes "Tno" because they're visually similar. And "Sn" gets replaced with "Sh", "nk" becomes
  "af" etc.

  Then I'd apply this ligature set to open source fonts to make things like "Stability New Roman" or
   "Stability Sans Mono" etc.

  How would we go about doing this?

What Should Happen?

It shouldn't refuse. It's a benign request about font creation.
