Try using your function with a filter.  This filter might work:
org-export-filter-headline-functions.  Of course it goes without saying
you will have to update your function.

A very simple test tells me this is probably going to be backend
specific.  I have had this query about filters for a while now, how to
write filters that are backend agnostic.  I think I'll start a new
thread once I have formulated my question more clearly.

Hope this helps,
