I know this reply will come trully late, but I just saw this post. By the CRL, you can use a Episode IV and V Luke's graflex Lightsaber style, so yeah, that will work.
Also, you can actually build one trully easy, this is the one I made from 2 PVC pipes, the "tongue" at the middle was for the on/off button, it ended being too long, anyway, i kept is that way, just 2 pvc pipes, few screws, a couple of buttons and aluminion pieces, and you can easily get your own Starkiller style lightsaber to carry at your belt.
