Here's a "toggling" version :
(defun my-toggle-hide-region (beg end)
"Hide region. Unless it contains already hidden text, then show it."
(interactive "r")
(let ((has-invisible-p
(catch 'invisible
(dolist (ov (overlays-in beg end))
(when (eq 'outline (overlay-get ov 'invisible))
(throw 'invisible t))))))
(outline-flag-region beg end (not has-invisible-p))))
