Unfortunately, morphs are not interchangeable between different models.  Poses, on the other hand, will work depending on the vendor.  Some work well, others need tweaking.  If you have the "Save as Universal Pose" checked in the General Preferences, you can resave a pose as a Universal Pose.  IIRC, if you click the double check icon at the bottom of the Library, the selected pose will be applied as a Universal Pose.
