I had a similar theory about the Raths having Pink and Azure being Mating Season forms (like Black Diablos) and Silver and Gold being old Raths having lost its sexual hormone production. But well, you can have every theory you may but if Capcom says it is like that it is (unfortunately or not) like that.
