When reading this tread, I was curious to see if I could do something like this so here is my attempt at it with Genesis 9 and the Kat morph applied.

In Daz Studio load Genesis 9 and apply Kat to it. With the Scene tab selected Genesis figure transform it to TriAx Weight.

Export the Figure as CR2 File.

Load by drag and drop the Figure in Poser. Slide to frame 30 and use the DUF pose converter script made by Ken1171_Designs and available here at Renderosity to set a pose or manually pose the Figure. One problem here is that the shoulder can only be rotated a little or it deforms the breast. Other than this all seems to work well.

If you want load some dynamic clothing. In my example I used some clothing made for LaFemme2 and scaled to fit more or less Genesis. I also ported over the Genesis Eyes and the Voss hair and conformed those new Figures to Genesis 9. Specially the Eyes were needing some tweaks in the materials and they still are not perfect but my goal was more to see if and how I can load Genesis in Poser so I did not go more in deep for this as it is only messing around in the material room.
