The plan is to replicate or fail to replicate all 2008 articles from three major Psychology journals.
ETA: http://openscienceframework.org/ is the homepage of the group behind this. It's still in Beta, but will eventually include some nifty looking science toolkits in addition to the reproducibility project.
I would bet this is totally impractical for most studies. In the medical sciences the cost is prohibitive and for many other studies you need permission to experiment on organisms (especially hard when humans or human tissues are involved). Perhaps it would be easier for some of the soft sciences, but even psychology studies often work with human subjects and that would require non-trivial approval.
Finding participants is already one of the biggest bottlenecks in psychology research, and it would get worse in shend's scenario, because the supply of participants is fairly inelastic.
