I don't think this specific (Facom) mod has been done here before, but has obviously been done with other ratchets. I got the idea to do this from an article posted in the Nepros thread, so no credit due to me apart from the 5 minutes of work.
Anyhow, pretty straight forward; if there's anything not apparent in the photos, feel free to ask.
I started with a Facom R.161 (1/4") and a J.161 (3/4"):
