The idea of using an offset red dot as a primary optic for close range shooting, with an LPVO (or ACOG) at 12:00 for mid to long range targets, isn't really new either.
Multigun competition shooters have been doing this in open/unlimited division for quite a while.
Jerry M is one example. He's been doing it since at least 2008 (the first time I remember seeing him with an offset dot at a match), probably longer.
A YouTube vid from back in 2013:

That dot isn't being used as a "backup" optic...
But I think this thread is supposed to be about a rifle that's useful with NVG as well as in daylight. If your 1.93 offset mount will work with NODs, I suppose that's more inline with the spirit of the thread than a dot at lower 1/3 or absolute cowitness height.
