If they were a god of healing or a fountain spirit, that would be the kind of thing, yeah.

Though I'd say something like curing disease rather than healing damage. Maybe give them the ability to cast Heal once a week in the passive power.

I'm thinking a Vanir of Fortune
Maybe War
Feasting
Commerce
River spirit?
Thunder/storms...kind of thing you'd pray to for rain
Fire
Vanir of the winds?
Death...

Some of them might have more generic abilities like spellcasting and so on, especially at high level.
