Traditional Porch Post Design Needed

I’m building a new front porch with a footprint that isn’t a perfect rectangle, so the support posts must follow an irregular line while still reading as classic, time-honored millwork. I already know the structure is sound; what I need now is your design eye and engineering skill to turn my rough carpenter’s layout into fully detailed post drawings that match a traditional style.

Here’s what I’m expecting: letter with a drawing supporting the design. Would like to use something like a simpson ABU66Z or 88Z.
