How does Cauliflower and Potato Grattin Sound?

I think it sounds quite nice, to eat along side some butter baked chicken, I have looked on the internet and it seems this concoction has been done before, So I will make my usual cauliflower cheese recipe, with a slightly thicker sauce then layer thin sliced potatoes in my pie dish, top with cheese sauce, more potatoes, more sauce and then the cauliflower and finally more cheese sauce.
