I have used V4 poses on G2F.  They work fairly well. There is a product in the DAZ store called Handy Dandy by Slosh. It has presets to fix G2F hand and foot poses after you use a V4 pose on G2F. With those fixes V4 poses work fairly well on G2F. You will still need to make some minor adjustments, but that is always true of poses.
