As someone who's used a Quest 2 for hours and hours with a heavy 3rd party head strap, over-the-ear headphones, and a battery pack strapped to my head I wouldn't worry about the weight too much. Even playing intense games where I had to move my head a lot it was never my neck/back that hurt--it was always my arms, haha. That's really going to be the new RSI waiting to happen: Moving your hands in the air constantly. Try this: Pretend you're scrolling a really long web page a little bit at a time by holding your hand in the air (in front of your face) and doing a pinch with your fingers like you're grabbing something, lifting it up, then dropping it again. Do this motion very slowly (like you're reading) for like 10 minutes straight, over and over again. Now do the same thing, pretending you're looking up at a VR "window" or down at one. How do you think your arms will do after existing in this VR environment for hours at a time? :D As long as we can scroll/navigate with the keyboard everything should be good though
