I would love to see this. My frustration with sourdough recipes and websites is that too often they give instructions but skip the fundamentals that would allow the reader to truly understand what is going on and diagnose issues or customize for their desired outcome. Also, most recipes seem to focus on round loafs baked in cast iron pans. I have done this successfully but find the shape extremely inefficient for my preferred use (sandwiches) relative to a longer, more rectangular shape. (E.g. for toasting). As soon as you want to get away from this, the resources available shrink by at least an order of magnitude or two, and I have not been able to achieve the same crust since!
