If this existed in the real canon, then Yoda would have known since they say this came from the Jedi archive!! This would have been explained to Luke or even Ben & would have been used to end the empire before it began!!! This is proof Disney had no care in the world for Star Wars & the fans!!! If they had cared, they would have stayed true to origin!!! They only care about getting people's money!! True fans will or have already thought about this!!
