actually they are not. if you look at the list of Kekkei Genkai on this very website we are aon not once is Amaterasu or Tsukoyomi listed the only thing related to either that is listed is Sasukes Blaze release which is a Kekkei genkai of Itachi and Sasuke Both Amaterasu and Tsukoyomi are simply classified Dojutsu(eye techniques) they are associated with KG because only KG users can cast them so yes in theory since Kakashi already had a KG he could possibly copy it. also the manga backs up that theory being that when he pulled off PS naruto said"well he is Copy kakashi" and sasuke said that is besides the point he should not have the sharingan" this indicates that those who have the sharingan can possibly copy the unique techniques of other sharingan users.
