Goku was sent to earth to destroy humanity anyway right? So actually this is almost the Goku that would have existed if he hadn't hit his head and turned 'nice'.
As of Dragonball Minus that isn't really right anymore. It's revealed that Bardock and Ginne sent him to Earth just because it was a remote and weak planet, and so it'd be easier for him to survive there. The goal was to get him away from the Freeza stuff, not conquer the planet for him. The Galactic Patrol detects his ship though, and think that he was sent to conquer the world.
So, I think the new backstory pretty much rules out Goku Black from being just "Kakarot" from some alternate timeline. His earrings, which have a design like the ones of the gods, also clash with that idea.
