Bisquick has a lower fat, and sodium version, not too bad. Unfortunately, since my stroke, I have had to find lower type everything too. Buttermilk can be replicated by using the lowest fat milk you can find, and add 2 tablespoons white vinegar to your milk, and allow to sit on counter until it thickens, and will perform similar to buttermilk, use a bit more baking powder and it works well. Gook Luck.
