If this is about your personal needs, why not make a keyboard macro to
achieve what you want, and use it thereafter?  IMO, we shouldn't add
to Emacs stuff that is needed by a single user (or a small number of
users) because of their peculiar workflows, and which makes little
sense with other workflows.  Inventing characters at kill time sounds
very strange an unintuitive behavior, so adding it to Emacs, even as
an option, would be a mistake, IMO.
