Not likely, they need to be stripped down to fit the lower comp pistons, and the supercharger inlet assembly needs to be fitted plus whatever bits are needed to fit it to the Falcon, and the extra demand should mean no loss of jobs. According to one of the guys on FF that is, and he knows. Adds credence to when Rod Barrett said they would still keep the assembly line here. Its just that now they won't need all the custom parts the 5.4 requires bar pistons, inlet manifold etc.
