Is it possible to expand the world space?

[xaosbob]

I understand that the DLCs and a number of mods create new world spaces for their content, and many other mods add interior cell content or modify existing world cells for exteriors, but is it possible to expand the DC Wasteland world space (or the Mojave Wasteland in NV) directly?

 

This is my thought: the DC Wasteland world map is x exterior cells wide by (assumedly the same) x exterior cells high. I haven't yet really dug into the GECK, so I don't know the actual number, but so we can use numbers, say it's twenty by twenty, for a total of 400 cells. Is it possible to append a contiguous row or column of exterior cells to the edge of the existing map, both accessible in the world space and visible on the PipBoy map? Now, adding one or the other would skew the squareness (now it is 20 columns by 21 rows, or vice versa), so if equal numbers of each is important, can we append one of each, to make a 21x21 grid, for a total of 441 exterior cells--41 new ones to play with? Or, taking it one logical step farther, a row/column to each side, growing the map one cell in each direction for a total of 484 cells (84 new)?

 

The "physical" worldspace actually already extends a distance--if you noclip past the invisible wall or switch it off, you can wander "out of the box" for a good while before things make no visual sense anymore, and that includes DLC world spaces (though most of Zeta is interior and the Pitt may actually have sharper borders, considering it's pretty well ringed with ruins--haven't checked there). In theory, it should be possible to somehow use at least those built-but-empty cells, shouldn't it? What about expanding the "landmass" itself?
