Maybe you can try this (not heavily tested):

(defun my-update-day-name-in-inactive-time-stamps ()
  "Update the abbreviate day name in inactive time-stamps."
  (interactive)
  (save-excursion
    (goto-char (point-min))
    (while (re-search-forward 
	    "\\[\\([0-9]\\{4\\}-[0-9]\\{2\\}-[0-9]\\{2\\}\\)\\( [a-z]+\\)\\]" nil t)
      (let* ((date (match-string 1))
	     (day (format-time-string
		   "%a"
		   (apply 'encode-time 
			  (save-match-data (org-parse-time-string date))))))
	(replace-match (concat "[" date " " day "]") t t)))))
