You're going to have to sort of do this from scratch. Assuming your cameras are solidly fixed, so the relationship doesn't change, you can do it pretty easily. Find the registration between the cameras by looking where they overlap and matching feature points.
The hard part is finding the warp from each of the six images to the final frame. That sort of advice is far to particular to your format and cameras for us to help with.
You can use the Image Blenders from the stitching module to help out.
