It could be done in 5e.On Ch 2: I admit I am intrigued by the idea of playing in a way that insulates the players from the rules. It doesn't seem possible with modern D&D, but could conceivably work well with more narrative games.
Have a copy of their sheets. Have them declare their actions, but you handle the rolls where you can, then declare results.
This will be more immersive for them and take a bunch of rules out from immediate view from the player perspective. Downside is losing the fun of actively rolling. And the extra work for the DM. Players will still track things like slots and gear and hp. Extreme no visible rules would not even say hp, just wounded or not. Which would mess with judging healing a bunch.
