No, you'll need servers and enough network capacity to handle the load, an understanding and supportive hosting provider, a law degree or enough money to pay somebody with one to keep you out of court/jail/prison, a network of degenerates to provide traffic and content and/or a copy of the existing 4chan content, a stomach of steel to deal with the content moderation duties, and a moral compass so warped you think hosting degrading and illegal content is "just liberalism and freedom of speech" and not something that needs a second thought by any right-minded person.
But sure, if you have all that and the source code, you're all set. Godspeed!
