Hmm. Not necessarily. If you're speaking strictly from the point of view of sharing knowledge, well, there's nothing really stopping that now. But if we're talking about moving computer science departments into social science departments under the pretext of sharing knowledge, I'm not sure that's necessarily a good thing. It might be, but I'm not sure.
What would the effect be of putting physics in the social science departments? Or mechanical engineering? I think if you can answer that question, you can answer it for computer science, and by extension you could just say you could introduce all of these programs into the social science departments to share knowledge... in which case you could just have a university.
