I love the idea, but some feedback from a climatologist.
As a young post-doc I did mostly experimental work on clouds and this structure would have fitted well.
Now I do climatology and work with data others have generated (we need data over centuries from all over the world), as well as many methodological work (propose new analysis methods or test them). With my current work this structure would either not add value (were problem, method, analysis and interpretation do not make much sense individually) or for some theoretical papers be impossible (because it does not follow this structure at all).
So maybe we need an additional flexible category, were people are allowed to dump whatever is good science.
