That would be a winning application. Something that I expect you could get NASA/SpaceX on board with, send some sheets up as ride along payloads for a resupply mission, put them in the bay behind the Dragon module on the second stage with some cameras, then use dragon as an uplink to look for space debris impact on the second stage as it re-enters and monitor the results. I would have to know more about what is available in the remains of the second stage to know how much mass you would end up adding for the experiment but I expect it would be less than a couple of kilograms.
