I like what you've done here, but two points to mention regarding the Snow Ravens, their front line clusters use the more traditional clan organization, what you seem to have deemed the "Strict Clan Cluster," the triad organization you show is primarily limited to second line formations (this is mentioned in the Snow Raven Unit structure section, last sentence of the second paragraph, pg 123). One other thing is the Snow Raven's Wing Clusters, purely aerospace formations of 5 binaries of fighters (Snow Raven Unit Structure, 4th paragraph, pg 123).
