Six Sided Periphery

It's not easy to fit P1e's maps of the Periphery onto the housebooks' map of the Inner Sphere. Some worlds match fine, but others - like in Morgraine's Valkyrate, or the district capitals of the Outworlds Alliance - get twisted around into new positions.

So I overlay the Periphery nations with the geographic territories and I notice that the six territories seem to butt up against the edges of a hexagon. Six territories, six sides - know what else has six sides? A cube! 

Different viewing angles would explain so many things about these P1e maps. There's a few ways a cube could be oriented; based on where the "Draconis Rift" is, though, I think it has to be the first of these:

The "Outer Sphere" is pretty obviously in the top-right corner; I assume the "Hyades Rim" runs along the bottom to the right; and the "Draconis Rift" looks like it runs along the top (but maybe not the very top) toward the top-rear corner. Much harder to guess how exactly the other three territories lie.
