Basically the Very Hard difficulty should just be 2-3 shots kill you and your enemies.
I don't think Ive ever seen or played a PVE game where it took same amount of hits to kill both you and your enemies. Usually "hard" means that you die in one shot while your enemies are bullet sponges. This goes for Witcher 3 too.
Sure, it would be cool and very Cyberpunk 2020-y, but I dont see it happening.
