Just so I have the context, what's the north and south face trick?
k, so for one, you can still make that whole thing 33% longer and wider
red = your element's size, green = max size
try this (you will probably have to to adjust the display settings)
Basically, what I did is toggle on "Rescale", which is usually used for something like diagonal (up/down) rails so that the element gets stretched to cover the whole distance between opposite corners even though the element is only 16 units long.
For some reason it also works on non-rotated cubes, makes them slightly bigger, and comes with the bonus that you can visually "move" the cube on 2 axes by changing the respective pivot point position. This works around the restriction of cubes only being allowe between -16 and 32, since the cube's position and size values never go past those thresholds, since we are only ever changing the pivot point values (which have no limit)
to change which 2 axis it can be moved with the pivot point values you need rotate the element on one axe back and forth once and then it swaps to the other 2 axis. (so if you rotate on Z back and forth once you can offset the element on X and Y axes with the X and Y pivot point values)
To be fair, that's a fairly niche/complex/unituitive way to break the rules xP
I hardly ever see anyone use it, but for flat stuff it works
you could go bigger by repeating what I did
you could also use bigger base elements than I did (mine are just 32x32, and they could be 48x48)
I used 4 of them, but you could repeat that to 9 or more
as I said, pivot point positions have no limit, so this could be repeated endlessly (within technological limits)
last pivot
as I said, if you rotate it on one axis back and forth once it will let you move the element on the other 2 axes with the pivot points
in your case you wanna rotate on Z once and then move stuff around on X and Y by changing the X and Y pivot point values
