One could build out some kind of table logic to handle it for a subset I guess, but it appears to just be largely impractical to me with their design. A flaw I think, but not sure it's really solvable.

Depends on how many integrations you need. There likely will be an example of supporting two distinct integrations with Duo, courtesy of the University of Florida needing such (for standard commercial Duo and a Duo FISMA service). I suppose that could provide an example to extrapolate to a few more, but as Scott indicates, I don't think you could go much farther and have it be easily manageable without some new design.  The version to support two started with the Duo plugin on the Unicon GitHub site, and will be available more generally once fully vetted and "generalized".
