Yeah, that sounds similar to the idea of the Terrascope. I think the positioning of drones for the sun might be so wide to be infeasible for the next century. (Like, the drones would have to be in the Kuiper belt)

I haven't watched this YT video recently, but I think he also touches on a Sol-scope and a Jupiter-scope https://www.youtube.com/watch?v=jgOTZe07eHA
