fbt for future meta hedsetas

So I was doing some thinking and I know that the quest 3 has upper body tracking, and I might have some form of a solution for camera based lower body tacking using the headset itself (for future headsets). So what I was thinking was that the front of the headset could have a small camera angled downwards in the front and the headset would have some form of elite strap with a camera tilting down on the back. With Meta getting into AI and all they could use AI to simulate the blind spots and to stitch the 2 camera's together. I have made an example here using the quest 3's proportions. Just the feet would be tracked and the rest would be AI IK. and as you can see the blind spots realy arent an issue execpt for under the hips, and if one where to sit it would a form of advanced AI IK that was shown off before. This mostly means the advanced AI IK that they showed of would be mostly runing the show but the cameras would heavly aid it.
