This seems totally obvious. Has anyone proposed it before?
Yes, on Usenet, and it looks like the authors also thought of using it on
email as well. It's called yEnc:

I don't think there was ever an RFC, though.
I found a discussion on this very list in 2003 of gzip-8bit which was more
or less gzip with yEnc escapes, and a draft that Ned wrote:
