The minimum weight for a sunshield is the same as a solar sail (and in fact will be one and can use that for station keeping, though you may have to play games with albedo to avoid having it just blow away), and there's extant proposals that are on the order of 0.1g/m^2 or about 11 million tons for the entire thing, with no reactionless drives or anything similar involved.
