"Sci-Hub is a shadow library website that provides free access to millions of research papers and books, without regard to copyright, by bypassing publishers' paywalls," source: Wikipedia. "Sci-Hub obtains paywalled articles using leaked credentials." So, it seems, Sci-Hub focuses on papers owned by corporations, rather than individuals.
There's surely less interest in providing access to papers owned by individuals, since those individuals can simply make their papers publicly available. Nonetheless, let us suppose that Sci-Hub takes an interest in making more works available. Then you just need to make papers available where Sci-Hub looks.
Even technical report repositories such as arxiv may forbid Sci-Hub from redistributing papers. So, there isn't much of an incentive for Sci-Hub to move into this space: They create trouble for little reward.
Sci-Hub could start looking at personal websites, but, what's the reward? The material is already accessible. Sci-Hub could also start allowing authors to upload content, but, again, what's the reward?
I don't really see why Sci-Hub would invest in making papers owned by individuals more accessible. Their niche is elsewhere.
