Drop the cameras and microphones and replace them with a couple accelerometers and gyros. Paired with your phone's GPS tracking, the glasses can tell where you're looking without actually seeing anything. You can get handy features like a floating 'turn here' sign over your exit while driving with GPS navigation without recording anyone or anything at any time. Better battery life, too.
I don't think that would work particularly well with AR: People get sick if movement isn't synced up properly, not having any sort of cameras or sensors at all would exacerbate that problem.
If you are talking about a simple HUD, then that might be a lot more viable, but for AR and the tech we currently have, some sort of camera or sensor array is kind of a requirement practically speaking.
See, I don't really want full AR. I want a HUD, a very small number of rudimentary AR features, like floating windows for text documents or videos, physical buttons on the arms of the glasses, small drivers by the ears for audio, and battery life that will last most of the day. I already have to wear glasses and if I'm paying more for extra features I want ones that will last the whole time I might want them, not just the six or so hours a day that the current offerings have.
If that's all you want, making something that just clips onto your existing glasses might be pretty viable.
GNSS isn't really accurate enough for this, especially in urban environments where there is poor line of sight to most of the satellites.
