Hmm; I don't think we fully understand each other.
Absolutely do the study; in fact, do several.
What then, though? A "study of studies", or any method of reconciling or making sense of these multiple studies, is the "meta analysis" in question. It's going to happen, in some way, somehow, by somebody. There is no way to reconcile multiple studies without doing some form of what we are calling meta-analysis. Even if it's just you or me googling it up and then deciding which of the studies to trust, that's a "meta-analysis".
My claim, therefore, is that it's far better to acknowledge this need and reality, and have dedicated teams of experienced professionals do it with an open, consistent method; then for each of us to mentally, subconsciously, "biasedly", to pick & choose and prioritize the studies.
[in the end, proper meta-analysis, and study replication, are the methods of how we discover inconsistency, contradiction, data issues, or other problems, whether in psychology or other domains. It's not a method of "fixing something", but a method of collecting, analyzing, and reporting on multiple studies and data points]
