It would look something like what I posted below in this post, but I have no idea how Mr. Z build his screens. It's so incredibly confangled in how he actually put it together that it's tripping me up every few pixels. I'm still trying to rip all his tiles in. If I could have a perfect color to color, pixel to pixel conversion, that'd be excellent.
So yeah, it'd look something like that, more or less. Maybe a little larger with some Z3-type walls, though I personally prefer to avoid the grandiose and pointless in favor of the petite and practical. :p
