It's not noticably wider... There might be a slight difference in the thickness of the side plates, but it's effectively the same size. See here (second from the right)
But yeah, making it a razorback is the same as for any other rhino. Not sure if Forgeworld still have a las/

GW plasma guns, and both weapons have been attached with magnets for 'Weapon Destroyed' removal.
