That's a tremendously expensive way to detect fraud. There's funding, but also the people replicating need to have at least near the expertise of the original authors, and the rate of false positives is clearly going to be high. Mistakes on the part of the replicator will look the same as scientific fraud. Maybe most worryingly, the negative impact of human studies would be doubled. More than doubled, probably- look at how many people claimed to successfully replicate LK-99. A paper may need to be replicated many time to identify unknown. Maybe first we could just try specifically looking for fraud? Like recording data with 3rd parties (ensuring that falsified data will at least be recorded suspiciously), or a body that looks for fabricated data or photoshopped figures?
