I might be missing something from your description, but would this work:

1) Use Copy Link on a OmniFocus project
2) Paste the OmniFocus link into a TextEdit document
3) Drag the link from the TextEdit document into your project folder in the finder.
4) Change file name from task/jexW10LHv6C to "Friday Report"

I'm sure one use Automator to construct a script which would automate much of this process.
