Actually, I think there are CFFs with Type 1 charstrings out there in
the wild, but it is definitely not the rule but rather the result of
poor conversion of Type 1 fonts to the CFF format.

This is not possible.  According to people from both Adobe and
Microsoft (as discussed on the OpenType mailing list, IIRC), a CFF
font in an SFNT wrapper can only have a single font.  This is
undocumented, however.
