If shinobi not of senju or offshoots are able to contain bI juubi so can he as an Uchiha... he can apply NE to his susanoo as well as envelope kyuubi with susanoo while also having reshaped larger amounts of chakra effortlessly in seconds on par to the first to ever do it.
It's mostly about strong will outside genetics.. and Sasuke has both so kyuubi would get rekt in a tug of war lol
No, Hagoromo became a Jinchuuriki because of his body, Ashura inherited that body power, Uchiha did not. Uchiha only inherited the power to control bijuu with genjutsu otherwise the tablet would have mentioned them being able to become their host.
1. Sasuke doesn't have the will power to tame Kurama because he's prone to hatred like every Uchiha.
2. He doesn't have the chakra reserves to use KCM of a bijuu that's not friends with him
3. He doesn't have the personality to befriend Kurama therefore will never awaken BM
4. He doesn't have the sealing talent to bind a freed Kurama, therefore can't unlock KCM
5. He doesn't have the body to master NE on the level of Ashura.
And finally, Kurama mentioned Naruto's
bloodline being the reason he was compatible with bijuu chakra and able to use it to the hghest extent. Sasuke isn't an Uzumaki and isn't an Ashura transmigrant therefore will never have the body to be a Jinchuuriki to the same extent as Naruto.
