I have, I have come to the same conclusions as you, and I have
implemented Option 4 for myself. However, I'll probably abandon it and
do instead something like the following to convert a file to DocBook
XML markup:

- call emacs as a batch job, using
  http://fly.srk.fer.hr/~hniksic/emacs/htmlize.el to convert the
  font-lock-highlighted buffer to HTML.

- Run the output through an XSLT processor to convert it to DocBook
  XML, using a stylesheet that is yet to be written :-).

htmlize.el claims to produce HTML 4.01, but my quick test validated as
XHTML 1.1. The output looks quite clean; highlighting uses class
attributes and an embedded <style type="text/css"> definition. It
should be easy to write an XSLT style sheet to transform it to DocBook
XML. 

Or, one could change htmlize and call it docbookize. Or, perhaps
ideally, one could turn it into an xmlize and give it customization
options or different entry functions for different output
formats. Talk to its maintainer...

But it does not do HTML output, does it?
