2 left hands and 2 right hands?

I am trying to develop an environment in which the left controller moves to mirrored left hands with the same actions etc but an offset in position. Any ideas how I can do this? I have been trying to do this for 3 weeks without luck. I don't need anything very advanced, but something as simple as copying the already implemented hand, move it a bit and then make it work as well would be sufficient. I hope anyone can help me
