Why don't they revive the Scions are Twelve story?

[Diamente]

This is a throwback to 1.0 and it really bugs me that they subtly kept doing it with only 1 small change in casting up to 2.55. Each of the Scions have a blatant descriptive parallel to which of the Twelve they supposedly are manifestations of. Even Yugiri came onto the scene representing one of the remaining missing deities. Moonbryda obvious they changed name and gender on but kept the race accurate at least. But I don't see why they kept on this path but have done nothing with it. Maybe it's a 4.0 thing? It just claws at me that it's right there in front of us.
