Can potato flakes be whizzed up to substitute for potato flour?

I have a focaccia recipe that calls for some potato flour. I have potato flakes. I have oat flour, semolina, whole wheat pastry flour, buckwheat flour & a/p. Is my best bet processing the flakes into 'flour' or using something else. According to the recipe the purpose is to soften the crumb.

Leave it out. There's plenty going on already. And honestly, I've never seen a foccaccia recipe that's called for potato flour, at least not an Italian one.

You will have to cut back on the amount called for, by about 1/3 or more less flakes than potato flour..and pay attention to the moisture when you mix. But yes.
