That last picture is so right, the way a nice timeless tudor should look (maybe a couple inches off the top)

I have a combination of A front rails and box tubing from the toe boards back. Building your own is quite a project to keep squared up unless you have a frame jig. I have never had that luxury and you have to weld very carefully to keep the frame from warping, measure weld, measure, weld. Almost every weld requires remeasuring. Then there is the issue of holes and boxing. By the time you get all the holes filled in an A frame and get it boxed you have a tremendous amount of time invested.
