The title kinda says it call. Im not sure how easy it would be to do the import, unless you were to take it all and put it into a single page (converting into confluence-style code) and allow the user to split it up if he/she wishes.

The export would be much simpler and far more benificial to people in companies like our where managers prefer to pass word documents around attached to emails, but techies / developers prefer to edit things centrally.

I envisage the export working the same way that an export to PDF does, just to a Word document.
