Nope, not happening at least for the next year.
You really want to Awaken all three of those Hime, but in what order... Satan goes from -15% Def to -25% Def (and almost nothing else), Susanoo turns into a damage dealing beast and Thanatos goes from -20% Def to -25% (plus some other minor goodies).
So I guess Susanoo > Thanatos > Satan? Those three will make a very solid core for you to play around with, with a fourth Hime being swapped around depending on content. Make sure you grab the monthly Dragon Eye from Raid Medals, by the way. And join a proper Union for Union Dragonic Eye Shard rewards.
