The mirrors would require at least different door modules along with a possible bcm re program. I don't know if anyone has gotten their bcm re programmed yet. At least one person was told by the dealership that re programing bcm couldn't be done. There is quite a bit of hardware associated with the lane keeping system.
Ford doesn't offer these things in North America because people wouldn't buy such a small car with the price tag of a European optioned focus.
