Daz3d to maya back to daz3d

I have been researching this for far too long. Over a year of videos, Forums, trouble shooting, and exploring. I just want to be able to bring Gen 8 into maya, add an animation to it, then bring it back into daz3d. I have tried the gen to gen 3 to gen 8 route. I have tried the FBX export using motion builder route I have tried putting the animation through maya into into blender, exporting out as a bvh then putting it back into daz The one that came the closes was the last one. Being able to put a daz character into maya, add a animation to it, then exporting it out as a fbx. Upload it to blender then export out as a bvh then put into daz. The problem is the bones During this process gen 8 has too many bones in their arms and legs. It messes up the mesh in with the animation file. A small adjustment of deleting the extra bones in maya would leave the character incompatible when put back into daz3d. If you deleted the bones in daz then trasfered over to maya, the missing bones are for the rotation of the arms. So the bending of the arms and legs work but there is no rotation. My question is. Is there a way to add roation to the joints of the arms in daz3d? Is there a way to merge the two joints into one? To have both the bend and the twist? Can I add a twist node to them? Is there a simpler solution i am missing???
