Having a higher threshold for publication can be imposed without detailing who does what work. You might argue that this means less research will get produced, but it's probably worth it. Practitioners underestimate the difficulty of transferring knowledge to outsiders because of frictions due to trust, clarity, and tacit knowledge.
When you call for everyone to scale their experiments up by sixfold, I think you also need to consider the logistics of doing that. I'm totally in favor of better, more rigorous experiments, but I know that we couldn't afford the time, space, or gear needed to do that right now.
