Reception Food Help! - Soup Bar?

Our wedding is late October next year. We live in the Blue Ridge Mountains where it quickly cools off in the evenings. We are trying to decide on our menu for the reception and would like to do something unique. We thought of doing a taco bar but just recently came up with the idea of doing the main entree as the following: a potato bar with various toppings, a soup bar with a handful of different options and then a grilled cheese station where you can pick what you want on it (type of cheese, ham, tomato, etc.) and they make it on a flat top. Has anyone done this before? Any thoughts or feedback someone can provide?
