Logically, Primals are fueled by the the crystals, and if Odin is a primal, he wouldn't derive his power from Dalamud.
Unless, the sundering of Dalamud (which was soley created to diminish Odin's power) fully unleashes him on Eorzea, or, another possibility is that the Primals themselves summon Odin to shatter Dalamud to free them from their bind.
Hmmm....Primals summoning an Elder Primal, I rather like that idea.
