I like this approach a whole lot, and would have suggested it to my GM if we were still doing 5E. But in the context of bullets vs. HP I don't think it works at all. Maybe if people have body armor and those initial rounds are always assumed to be catching them in the vest...but that would get pretty silly pretty fast.In every edition of D&D, since the beginning, I have used HP to represent 'toughness'. When you get hit for damage, it is not a real wound - it is scrapes, bruises, bangs and bumps. When you get a healing spell, it replenishes you by curing these minor impacts. I only describe an attack as dealing an actual wound when it takes someone down, or if it puts them close enough to be within one strike of death. It is a subtle clue to my parties that enemies are weak.
When it comes to gunplay, or archery, or any other piercing attack, I usually describe the blows as glancing blows or near misses that had to be dodged awkwardly.
This approach has allowed me to make great narratives without treating hp as meat points. It takes some practice, and at high level gets a bit odd with so many near misses/glancing blows at times, but usually by then the players have seeped into it and do not register it the same way a stranger to the table would.
I'm not saying this as a knock on D&D, btw. I think systems are best when they're tuned to a given genre/setting/tone, and while I think HP can be goofy af sometimes, the way you're interpreting it fits well in a mythic, high-fantasy context.
EDIT: Forgot to add that I just don't think bullets/guns work with D&D-style fantasy, the same way that a guy charging into a modern gunfight with a wooden shield wouldn't work. I know there are tons on here that disagree, but I don't think 5E or any derivative works as that kind of general toolbox.
