That would be totally sufficient, but I have no idea how much work it would require.

Many modes introduce "non-standard” faces, so the lack of non-standard faces is not a significant problem I think (though I’d love to see faces for regexps, command execution (%x, `` as in sh-mode) and symbols/keywords (as they are present in many languages outside Ruby).
