Tools for FrameMaker > wiki markup?

I'm looking for ways to get our FrameMaker-source content into a wiki with minimal prep and cleanup required (i.e. preserving cross-references, graphics, TOCs, etc.). I'm also evaluating wikis, so the exact target is tbd and may depend partly on its import capabilities. We have RoboHelp (which we use to generate context-sensitive WebHelp) and MIF2Go. Could buy something else if the results were good.

We looked at Webworks' export. It looks great, but isn't editable wiki markup, so not what we're looking for.

As an example of the kind of kludge I'm hoping to avoid, a case study on going from Frame to Confluence via prep with FrameScript, generating Java Help with MIF2Go, and converting the Java Help to wiki markup with a FAR script:

I tried generating .rtf with MIF2Go, converting that to .doc, and using Confluence's Word import, results are pretty rough.
