I think you'll have to rewrite the Deity move, in particular the domains. You can make two per element, or even three, ala Exalted (Ascendant, resplendent and descendant). That's a total of 12 choices for the player.
Maybe:
the fire that warms, the Fire that guides, the fire that burns
The Fount of Life, the Freezing cold, the All - consuming Abyss
ecc.
From the I-read-a-book-about-runes-once wisdom of Uzio Parp
The thing talker move of the druid (element talker) might be an interesting substitute for Divine guidance.
In general, the Druid - Cleric mix/multiclass is worth talking about with the player.
