If you really are a Creative then you need a Harmonizer regardless of the socionics relationships. But I also see some D+C so that might function sometimes.
If you use 2 subtypes there is a risk that you are not gonna get the desired precision for a realistic match.
I have dated duals of the "wrong" subtypes and there is clearly some basic flaw in such a relationship. DCNH is imo the basis of any stable relationship.
