Imagine a rear wheel with the DS spokes anchored on the NDS brake track - a huge improvement in spoke tension balance.
I'll reference my commuter rear wheel, built with an IRD Cadence VSR rim and American Classic hub with 80% of DS tension on the NDS. All heads-out of the NDS would likely get me another 5%. If they made a disc road hub at 130mm (and if my frame had a rear disc mount), presumably the balance would get even better though my wheel wouldn't be any stronger laterally. Your idea would likely get truly balanced tension, perhaps even allowing normal nipple-at-the-rim for the NDS.
It would be something fun to draw up in CAD if I ever get that bored. But as you say, given the minimal potential gains, I'll need to be really bored to put in that much effort!
