I like the idea, but there are a few questions I have for the plausibility of this approach. 1. Does mylar (or weight equivalent have enough reflectivity and flatness) to target a ground station? 2. How much light can be concentrated before becoming a risk (e.g., birds above solar panels, human eyes in vicinity)? 3. How fast will the mirror material degrade from solar wind and micrometeorites? I assume someone has considered this scenario previously, but I imagine that SpaceX lift capacity and price might change the economics.
