Rigging would only be half as difficult if Poser's Setup Room was dependable. Maybe E-frontier and Daz have a special edition of Poser that actually functions while the masses are provided with a version intended to curtail competition? 

They make more money off people buying content, and havinng 3rd parites sell their content through them. Doing what you are suggesting would be like cutting one's nose off. 

But, it's very possible that 'the pros' have better ways of rigging, rather then the setup room.
