We've talked about bolt-on ablative shields for operational vehicles derived from ERPS test beds: land, take off the old TPS, bolt on the new one, go flying. Might refurb the old TPS, might toss it, doesn't matter. That choice affects the financial model, but not the operational model.
The Chrysler SERV proposal used a system of large, bolt-on ablative panels. Something similar would work well for a DC-X style future vehicle.
