Yes. Genesis/Genesis 2 can be imported into Poser using the DSON Importer. This will, at least, make those figures compatible with Poser. There is a way to import G3F, but since it is only a DS only figure, the process is convoluted. Also, because the face morphs are rigged, G3F expressions will not work at all in Poser. Now. I don't think you will be able to reverse the process from Poser to DS, but I could be wrong.
