Ah, I should have read the thread more carefully :)

So this turned out to be somewhat tricky.  I was able to adjust my
previous code so that every subtree will be promoted to a top-level
heading before export by adding the following (this change can also be
seen in my published code here [1]).

--8<---------------cut here---------------start------------->8---
                (let ((level (- (org-outline-level) 1))
                      (contents (buffer-substring (point-min) (point-max))))
                  (dotimes (n level nil) (org-promote-subtree))
                  (setq html (org-export-as-html nil nil nil 'string t nil))
                  (set-buffer org-buffer)
                  (delete-region (point-min) (point-max))
                  (insert contents)
--8<---------------cut here---------------end--------------->8---

Hope this helps. Cheers -- Eric
