Help converting soup recipe to keto.

Hi, I miss doing this recipe so much, but dont want to get out of ketosis.

Im not that good coming up with recipes, so I've been thinking on subbing carrots for bell peppers, and milk for cream cheese. Now, about the flour... could I just sub with almond flour? I see some of the recipes just adding xantan gum for adding thickness, but I dont know why just not replace it with almond flour... Any insights are very welcome!
