I Believe that you are looking for something like this? it is just a quick mirroring , but actually would not be anything really new having a bridge between poser and Blender. I usually use it in the opposite way Exporting to Blender actually also preserves all the articulation if there are any that allows you posing your Environment in Blender.

I did not convert the trans when I mirrored the scene so it is kept as a simple sample of what can already be done no matter how big your scene is.
