best non dairy substitute? will almond milk or coconut milk creamer work as well?

I would sub coconut cream for the cream part, and coconut or soy milk for the milk; coconut's richness is perfect in pumpkin pies. Not sure about the almond milk or creamer though, I'm assuming that both would make the pie less rich, and the creamer may have other ingredients added to it such as sugar which would change the proportion of the ingredients in the recipe.

I would sub coconut milk, it's higher fat than soy and works better.

I make a non-dairy pumpkin pie using soy milk which works really well.
