Can a failed research become the object of research?
Meta-science/meta-research is the discipline that deals with studies that use the research methods to study research itself. Its currently quite en vogue, I don't know if you could make your study fit into this category.
Personally my two most successful papers are about what would have been quite mundane studies but anomalies in the analysis lead me to identify problems with the way data was commonly analysed across the whole field.
