Credit to the original thought to both Jonathan for the concept of "wings" and labcoat for the concept of "social contribution".
I thin, in addition to DCNH, there's a disparate kind of subtype: our secondary social role, as drive by our ID.
Any individual type will tend toward behaviours in line with either their Mirage or their Semi-dual. For example, an SLE-like SEI, vs an IEE-like SEI: an SEI who is critical of people's thoughts and their reasoning and more consistently seeks to perform their "Mediator" role through making their environment more rational and logical (like myself), or an SEI who more consistently seeks to build bridges between people and foster mutual understanding (an IEI in this case, but someone like Sigma). Obviously any individual will manifest both types of behaviours but gravitate toward one or the other more. This is because both wings are mutually interdependent in service of the types primary social role.
This exists on a different, but perhaps not irreconcilable level, to DCNH, owing on the most obvious level to the fact that one is a system of two subtypes, while one is a system of four.
DCNH is also concerned with group roles, while wings are more concerned with "niche" and one's independent approach to their social role; or other socially productive/worthwhile pursuits (for example, ILEs' wing-pursuits are probably not objectively socially productive, even if they're of interest to their introtim duals).
Semantically, I think you can have, for instance, Inventor-Lyricists and Inventor-Craftsmen, and Mediator-Conquerers and Mediator-Psychologists (less neat in the Mediators' case since Mediator-Conquerers often have a grasp of psychology due to their logical/rational/psychological approach to mediation; similarly with Inventor-Craftsmen producing beautiful works, and Inventor-Lyricists producing elegant and rigid/direct systems of thought).
