I don't know of any 3D CAD system which allows direct conversion to an older version. Most systems have to export a dumb solid (Parasolid, IGES, STEP, etc), which is then imported to the older version.
Does Wildfire not have a "Feature Recognition" module? In SolidWorks, the FR module will interrogate the model and convert (where possible) the dumb solid to editable features (revolves, extrudes, etc).
