I am not sure why you need to call 2 times, isn't once just enough?

I have tried this:

> (add-hook 'emacs-lisp-mode-hook #'outline-minor-mode)

and it works. I try that with this function here, could be
interesting. It creates new temporary buffers. C-u F5 and I choose the
favorite mode, and the above hook worked just well.

I think there is no need for second line above.

(defvar rcd-temp-buffer-mode-history nil)

(defun rcd-temp-buffer (&optional name mode)
  (interactive "p")
  (let* ((format "*RCD TEMPORARY BUFFER%s%s*")
	 (buffer (if name (format format ": " name) (format format "" ""))))
    (switch-to-buffer (generate-new-buffer "*RCD TEMPORARY BUFFER*"))
    (if current-prefix-arg
	(let* ((modes '("adoc-mode" "emacs-lisp-mode" "lisp-mode" "markdown-mode"
			 "org-mode" "sql-mode" "fundamental-mode" "html-mode"))
	       (mode (completing-read "Mode: " modes nil t nil 'rcd-temp-buffer-mode-history)))
	  (funcall (intern mode)))
    (funcall (intern (or mode "fundamental-mode"))))))

I don't think that is right place to define highlighting. Please first
verify options of outline-minor-mode-highlight (I did not yet).

I have tried that, does it work on your side? Not on mine, I don't
know why.

I have made new prefix: outline-minor-mode-prefix is C-c C-d "\x03\x04"

But TAB works automatically when you set headings.
