Just a note here - the Kaaputenen-Niarja jump is an incredibly long one, reaching across entire highsec "core" and roughly ~1/5 to 1/6 of the EVE cluster (based on a quick glance at the ingame map) in length. I severely doubt it is within cyno range.
Now my personal thoughts on this: It's not going to work. It would leave a colossal number of loose strings open storyline-wise (Khanid culture? lolololol, not anymore!) and have a number of technical difficulties, the least of which is the poor alignment of lowsec regions for a realignment of the conflict that way (Amarr and Caldari currently share only that one direct highsec route; Amarr and Gallente share at least lowsec 2 border systems and another only 2J through Minmatar lowsec).
So, yeah. Cooling of relations? Maybe. An outright, sudden, dramatic declaration of hostilities, in a time when we are trying to undo a lot of other outright, sudden, dramatic screwups? I certainly hope not.
