Something like

(defun TeX-local-list-setter (var value)
  (let ((old (symbol-value var)) tail)
    (dolist (buffer (buffer-list))
      (when (local-variable-p var buffer)
        (with-current-buffer buffer
          (setq tail (symbol-value var))
          (while (consp tail)
            (if (eq (cdr tail) old)
                (progn
                  (setcdr tail value)
                  (setq tail nil))
              (setq tail (cdr tail))))))))
  (custom-set-default var value))
