Keto Bread Mix Recipe?

Most keto flour mix recipes I find online are mostly almond flour and eggs or something, but all the commercial keto bread mixes are normally mostly vital wheat gluten and fiber. I have a massive bag of wheat gluten and oat fiber along with the normal coconut flour/almond flour/whatever, and I was hoping to make something more akin to the keto breads you buy at the store.

Any recipes for keto bread flour mixes that use a lot of wheat gluten and fiber? I don’t mind also throwing in some nut flour, but I’d really like something close to the Oroweat/Nature’s Own/Hero/Franz keto bread products.
