Christina Tosi uses King Arthur bread flour in her cookie recipes in Milk Bar. I hope your cookies are awesome.

They might be a little more tough than usual, but since most cookie recipes don't get lot of mixing or kneading, I bet they'll still turn out well.

At this point, it's already a sunk cost. You've made the three doughs, nothing will change that.

Just shape a couple of cookies from each, bake them and find out for yourself if you find the end product acceptable for whatever purpose you had in mind.

If the quality of a given bungled cookie dough is acceptable, proceed with baking off the rest of the batch. If something doesn't come up to your quality levels, then forget it, save yourself the time and expense (oven power).

You should have no problem. I ran out of AP flour and substituted my bread flour. Absolutely no difference in taste, texture or baking.
