The thrust surfaces on the #4 cap seem to be the tough part. I have not found anyone local to me (San Diego) that can do them.

And you probably already know this, but with splayed caps, you cannot run a dipstick in the normal location.
I like your saddle idea

I had a thought to address the thrust face. I was planning on bolting the No.4 cap on, indicate the amount of stock on the cap to the block face, then remove cap and cut measured step off clamped in a vise. Obviously do a semi finish and verify stock removal is on the right track and square.
