I think part of the problem is - what I imagine most educated people want(maybe I’m wrong) when they talk about this “diverse group of editors” is this like classically liberal view that is actually incredibly narrow when one looks at the range of more populist perspectives. Like thefp.com is probably somewhat close to what you describe but is the exact opposite of what I’m looking for.
What I want is this theoretical set of educated perspectives that claim to represent a broad range of views; when an actual broad range of views is more likely to include pizzagate than Burkian conservatism..
Maybe thefp.com would be a good starting point to ask - why is that not what you’re looking for? If you squint your eyes it provides a balanced perspective.
