I'm not an expert on fonts, but I don't think this is reliable enough.
Are you saying that a font might use the same glyph for similarly
looking characters from different scripts?  If that is true, then yes,
we could detect that.  But the fact that we have such a font doesn't
yet mean there is a problem worth warning the user, since these
characters need to be _used_ in a certain context to cause confusion.
