Actually, the more I think about this, the more it seems like this could be a good open-source project.
The idea would be to translate everything on Sci-Hub from PDF to MediaWiki and convert all of the references to links. That could be tough, probably loaded with edge cases. If it works though, not only would Sci-Hub be hosting all the papers but this site could make them all easy to find/navigate. Seems like it'd be super fun to go spelunking through a network of related science papers in a similar way to diving Wikipedia.
As an open-source project, it would also be possible for anyone to re-host the site in case it gets blocked.
