Sorry, I'm probably missing something, but I don't understand how this would work. Since each function would only be modifying their own local STRING variable, not the one that will actually be killed... Unless it's something like [in kill-region]: (let ((string (delete-and-extract-region beg end))) (run-hook-with-args 'before-kill-functions beg end #'string) ... Then the hook function would have to set the string by (defun foo-function (symbol) (set symbol "replacement string")) But that would be ridiculously arcane.
