I mean, look at it this way. Konoha's three noble clans or whatever, managed to keep their hiden jutsu secret from the Uchiha clan for decades. If the Uchiha Clan, most of whom are more skilled at using the Sharingan than Kakashi, couldn't copy Shadow Possesion, Expansion Jutsu or any Mind Transfer Justus, then how will Kakashi be able to copy them?
