I assume in the above sentence you meant that a comment to be a
heading has not to be indented. That is at least what I observed, and
was able to change:

In the setup code you provided (to be used with plain Outline minor
mode without outshine) with

  (setq outline-regexp "\\(;;[;]\\{1,8\\} \\|\\((defun\\)\\)")

when " *" is added at the beginning to respect indentation

  (setq outline-regexp " *\\(;;[;]\\{1,8\\} \\|\\((defun\\)\\)")

the indented comments are also considered a heading.

This makes me believe that in Outline major mode and maybe partly also
in Org mode even this

* Heading level 1
  * Heading level 2

could be made to work by tweaking outline-regexp and outline-level.
