Mark, the longer yard leads are already in the plans, if they'll fit. That version was just a quick mock-up to show you what the layout would look like with the yard in the center. The problem is the size/placement of the lower loop. The yellow line in Brian's photo would mean you'd come out of the loop and go right into a switch taking the "turnout" as the main and I'm not sure that's something you'll want to do, I don't believe it's prototypical either.
As you can see in the attached example, adding a switch to extend the leads is not as easy as it looks. However, once I expand the deck to 36" and maybe shrink the loop so the main can be moved to the right and a switch added to the left, maybe I can get things to fit. Shrinking the lower loop though will limit how long your trains can be, so we'll just have to see what works.
My understanding though is that you didn't plan to "work" the yard, so let me know if you want me to pursue these changes.
