That could certainly work! The intent, though, is not to track damage or hit points at all, but rather to handle wounds descriptively. When the player is about to do something that could get them hurt or killed, the GM gives a heads up, and calls for a roll if the player proceeds anyway. On a 1-2, the worst happens; in a 3-4, something less terrible happens.
So, let’s say the GM says, “You’re welcome to attack, but that opens you up to their attack, and the weapon they’re holding could probably kill you. You okay with that?” And let’s say the player says okay. If they roll a 1, they’re dead. If they roll a 3, they get hit badly enough to lose a body part, but they’ll live. Let’s say it’s a lost hand—that’ll hinder rolls later.
That sounds pretty unforgiving, but you can actually escape quite a few deadly scenarios by carrying around stuff you can break in defense. In the example above, if that player had armor, they could say that absorbs the blow, and they’re fine. If they had a cybernetic arm, they could say that absorbs the blow—that’ll hinder them later, but better than being dead. And so on.
Hope this helps! I don’t think you’ll break the game if you import HP rules from elsewhere, though. The game’s meant to be hacked, after all!
