Here's a paper I should have linked in my OP considering the idea at a very high level; https://arxiv.org/ftp/astro-ph/papers/0701/0701513.pdf https://arxiv.org/ftp/astro-ph/papers/0701/0701513.pdf That particular paper is considering an Earth-Moon Lagrange Point, which is much more accessible than Earth-Sun points, but the dust cloud would be highly visible in the night sky which IMO is disqualifying as long as other alternatives exist.
