I see value here. On the one hand, emotions are socially constructed. That may be well known and obvious, I don't know. On the other hand, I find specifying these axes useful: (un)pleasantness which is axiological, (un)certainty which is epistemological and the "(un)excitation" axis which is more "physical." Separating these components by analysing ones state seems like a useful exercise giving a finer grained view of the variables in play and what can be done with them. Though, yes, I don't think that it's novel that they are influenced by metabolism, that's a pretty basic consequence of materialism and we were taught that in psych 101. Maybe there are already existing models that cover this though.
