Board Thread:Theories and Speculation/@comment-3568954-20160825075414

so in his fight with Sasuke, itachi used Transcription seal: Amaterasu to cause sasuke's sharingan to temporarily turn into itachi's mangekyou sharingan and cast Amaterasu, when he comes before Madara(obito) its a temporary technique but sasuke in fact did get amaterasu perminently with his own mangekyou sharingan.

my theory or speculation is this.

could it be possible for Itachi to use transcription seal: to seal a sharingan technique into the eyes of anyone. like for example could he have used transcription seal: Tsukoyomi to seal the Tsukoyomi into Kakashi's Sharingan. or into a hyuga's byakugan. and if he could. do you think he could ensure that the transcription seal perminently effects the individuals eye. IE could he use transcription seal: Sharingan to perminently seal the Sharingan into the yes of a non uchiha. so that from that day forward they have a naturally occuring Sharingan.
