This is one of the next projects I'd like to work on, after I finish my PhD dissertation about unassisted birth this semester. I need to find some people to collaborate with who have experience in conducting quantitative studies on birth outcomes, in order to start a prospective study of UC (similar in design to the CPM2000 study, but with additional questions to reflect the unique circumstances of UC). It would probably take several years to gather enough numbers to have statistical significance, but I think it's important to have accurate information on the outcomes of UC, the health histories of women who do them, etc.
It would be a really big undertaking and would need to be done right, but I think it can and should be done.
