He could use the Poser stuff natively, but it depends on which version of Poser the item was built for.
Also, if the item leans on Python too much or uses Poser 11+ rigging, it will break in DAZ Studio (this is why Erogenesis' awesome Evolution One figure won't work in DS natively - he makes heavy use of Python and Poser 11-native rigging. Still makes me cry to think about it.)
Worth a shot in this case if it's just a bunch of spheres and cloud-like things.
