Dave Hayden of Austin Selectric Rescue is working on several type elements for the Selectric II: https://selectricrescue.org/

As I understand, the recent IBM Plex Mono face has been requested too.

It’s even the first link on this page. In addition to Comic Sans, he’s also made a font ball for Papyrus!

I can’t imagine using any of these (even when typewriters were king), but I love that they exist.
