Difficult, since we picked an agricultural god for main. It'd be hard to convey how they are relevant because while Crow touches upon some of their beliefs(likely in the form of the battlecrow, the crows feasting after a battle is iconic), most of our belief system is completely alien to their cultural sphere.
The tending of trees and care of the land The secrets of the world? The sun shines, the storm thunders, the grass grows and the crows feast upon the dead. That's their experience.
The "the grass grows" sort of is within the domain of our goddess though. Grass being better than usual has been the cause of most friendly hordes so far if I remember correctly. I agree with you that it wont be easy, but our choice of goddess isnt the worst fit.
Crow is actually worse I think, he has the problem that he is such an abstract dude that he will probably transform into some generic god of war and trickery within generations. All that stuff about teaching and curiousity doesnt fit at all with nomads and even within the people only shamans liked him before the temple (hopefully) changed things.
