It'd be cool if he re-established Root. His Root wouldn't be as dark and dirty as Danzo's, but he'd get to do the whole "working in the shadows" thing. Kishi wouldn't ever change his character to be all bubbly and social like Naruto. He'd never be able to walk amongst the common folk out and open under the sun. Like Itachi, Sasuke is forever in the darkness, but to bring about light.
Sasuke is good to the core. It's a different kind of good from Naruto's, but good nonetheless, and that's fine.
