I think it's easier said than done. Some conversions should be
straight-forward: turning a Source into an Enumerator, for example.
But others won't be possible without dirty hacks (e.g., Enumerator to
Source will likely require forking a thread and using Chan), while
others may be completely impossible (Enumeratee to Conduit). I agree
such a package is a good idea, and I'd be happy to help anyone who
wants to step up to the plate on it, but I'm not very hopeful that it
will be incredibly useful.
