Any changes you make to the PDF will make the existing signatures send
up a warning flag.  If you append your changes (rather than making a
"full save") however, the previous signatures can still find the version
of the document they signed.

If that last signature has yet to be signed, then change away.  If it
has... You're trying to do what all that signing technology exists to
prevent: changing a signed document.
