Hmm, I haven't done this.

Do you use Daz at all? If so have you tried dialing in the V4 shape for whichever version of Genesis your using. Apply the clothing/prop/hair or whatever it is to Genesis. Then export that item out as an OBJ which will fit V4. Then load the item into Poser and rig it? Better yet if you have V4 shape for the Genesis figure and can use it in Poser do the same steps as above without Daz but Poser instead. I know there are some morph tools that will allow you to transfer morphs to clothing items and there are some rigging tools to. Just maybe it is possible, might not be how I thought of  doing it but some how I think it would work.
