Coconut Milk substitute in a Skinny Pina Colada?

I found Langer's makes 5 calorie pineapple juice (3 parts), to 1 part white rum.

But I need 1 part coconut milk and the stuff is as bad on calories or worse then the alcohol.

Is there a good substitute?

​

My local smart and final has this, but I don't think it's the same coconut milk I'd need with a coconut taste. I think it's more like an almond or oat milk, made from coconuts, but not coconut tasting.
