I've actually made something very similar myself, as an experiment: a basic baked pasta dish with ground beef, tomato sauce sour cream and so on (lasagna in all but the shape of the pasta, really), with mashed sweet potatoes thrown in. And it was pretty good! Fundamentally, I don't see why it couldn't have been great in the hands of a better chef. Besides this sort of experimentation is how you make interesting, unique dishes. It's a lot of fun.
