Thanks, here attached is a patch doing that.

I noticed a problem: I can customize the unicode char just fine, but
whenever I try to customize the glyphless char and use `emacs -nw` it
doesn't work, it still uses "^"  or "v". My wild guess is that
`glyphless-char-display` is used instead of the custom table... if anyone
has an idea...
