Michael, Something analogous was proposed a few years ago by some engineers from Strathclyde University, Glasgow. They suggested capturing a near earth asteroid and using it to generate clouds of dust positioned at the L1 equilibrium point in between the Earth and Sun. See this poster on the proposal: http://www.strath.ac.uk/media/faculties/engineering/advancedspaceconceptslab/posters/10-06-08_Research_Day_Poster_-_Russell.pdf
