At first I was confused about how this would work, but thinking a little about it, it should be fairly easy. Give some researchers (randomly selected!) results from studies that are not RCTs ("control") and others RCT-based results ("treatment") to replicate. See which group manages to replicate more results. Expensive, yes. Would I like to see it? Heck yes, if nothing else as a way to trick the establishment into doing more replication studies.
