You'll need much better high-speed cameras than on existing glasses, and a really good beam steering mechanism coupled with much better laser than Blu-ray diodes. It'll be heavier than most VR goggles and very finicky. I don't even know which ones of fixed camera with a dual polygonal or standard 2-axis galvos or prism based PTZ with the camera doing classical lock-on and trained laser shooting from the opposite side of the camera. It's a >$50k project at benchtop static PoC level.

Put aside everything unethical and unworkable about it. Probably cheaper to lobby for a think-about-kids camera ban for products weighing less than 250g or contains transparent window apparatus that may or may not be curved in diameters larger than 10mm for fire risks or something.
