Maybe the OGR staff will build this as a project layout and present a series of articles on how they did it.
Well, that might have been a possibility some years ago when we (OGR) had a central headquarters here in Poland, Ohio, but these days there is no such animal (I believe a real estate firm or some such is currently occupying our old HQ). I work out of my home office in Poland, Ohio; Alan and LaKeeta Arnold work out of their home office in Arkansas; Jim Barrett works out of his home in Cincinnati, Ohio; and Ed Boyle works out of his home in Poland, Ohio. That's pretty much the complete core staff, not including my copy editor/proofreader, who is somewhere near the Ohio/Indiana border, I believe; my designer in Easton, PA; our fulfillment person in Indiana; and our printer in the Milwaukee area. So a project layout is, by default, no longer much of a possibility.
Besides my home layout, which is still very much in the "raw" state, the only other layout I am planning is a small all-tinplate layout with a winter/Christmas theme, just because I need a bit of a diversion to fuss with.
By the way: Plans are afoot to make Ken's track plans, which appear regularly in the pages of OGR, available as a Digital Subscriber Extra so folks who have a computer can view them in a much larger size on their home computer. Given the limitations of size of the printed page (we will nevertheless continue to publish them in the magazine), after such publication in the magazine we'll make them available in digital form for enlarged viewing. At least that is the plan.
