If you have a recent version of the shell, you can do this:

zle-line-init () {
  if [[ -n $copy_this ]]
zle -N zle-line-init
copythis() { copy_this="$*"; }

It's that complicated because CUTBUFFER only exists as a special
parameter once the line editor has started.

If you want to manipulate the editing stack (save the old value of the
the cut buffer onto the kill ring in the way the kill commands do) you
will need to use the array kill_ring.  See the function kill-word-match
distributed with the shell for an example.  (One day I should make it so
that copy-region-as-kill can take a string argument when called from an
editor widget.)
