So, do we know the degree of variability the non-fixed supports got this time around?

(By non-fixed supports, I mean those where an element is variable; so, mother-child, Shigure-father/sibiling, and Male Kanna-father/sibiling; at least following the Awakening equivalences)

The Awakening ones were quite copy-pastey and I was expecting Fates to follow that line, but then I heard Luna!Matoi has a quite unique one with her mother regarding her being a dead ringer for her grandmother, and now I am a bit curious...
