The merged mods worked perfectly, the strange angles bug turned out to be nothing to do with the mods. I added some new jump-back instructions in my own installation and this caused the sub to roll, probably do to Camera.dat settings.
This will work for any supermod, you would use that as your root installation. GWX3, NYGM or LSH3.
