I have no objection to the rules you put forth, or 5e raw rules. Still, I think any stealth ruleset would require a non trivial amount of design work.

Consider the fact that Bg3 doesn’t do group stealth checks. If the party tries to sneak around some guards, because sneaking outside cone of vision isn’t an auto success, every one rolls for stealth individually. That includes the plate-wearing, disadvantage-rolling paladin. The party’s stealth effectively becomes the stealth of the least dextrous, which doesn’t feel great.

So then maybe Larian adds group stealth checks? But how does the game know what a group is? Do we have to fiddle with the portraits? In any case, these questions and more would need answering.
If a single roll fails, then one could just keep their heavily armored 8-dex paladin ~30 feet behind, outside of the 360 degree enemy perception range. This is how it's often done in tabletop; the stealthy characters stealth a bit ahead (30-60 ft are the "standard" distances imo, but it'd be reasonable to shorten that to 20-30 ft for BG3 maps). This would work with enemies having either a single perception ring, or a smaller perception ring and a farther "sight" cone. Essentially you'd risk being detected with your tank a turn away for the chance of getting a surprise round.
