If he's been eating the substrate, putting in gravel instead is a recipe for disaster. He'll find it very difficult to pass any gravel pieces he ingests, and may end up dying of impaction. Stick with the coco-fiber, it's tried and true, and above all, safe.

As for the species not eating during breeding season, where did you get that information? Most frogs will still continue to eat, albeit with decreased appetites.
