I wonder if something like Anthologize -- http://anthologize.org/ -- would be useful for doing this.  From its "About" page:  

  Anthologize is a free, open-source, plugin that transforms
  WordPress 3.0 into a platform for publishing electronic texts.
  Grab posts from your WordPress blog, import feeds from external
  sites, or create new content directly within Anthologize. Then
  outline, order, and edit your work, crafting it into a single
  volume for export in several formats, including — in this release —
  PDF, ePUB, TEI.
