Retrofit of Panamera Turbo Rear Spoiler on Panamera or Panamera S?

[Geo3]

Wondering if a "flip-out" Turbo rear spoiler can be fitted in place of the Panamera or Panamera S rear spoiler?

Looks like it takes up the same folded space, so should just be a simple purchase of a Turbo spoiler, with mechanism, which should slot into same area.
