Damage scaling based on durability

Is there any way to change / scale the damage an item does based on its durability / damage value in a data pack with dynamic attributes? Or would that only be possible with a mod? I honestly don't know where I'd even begin to work on this idea, but its one of the key mechanics in a game I'm working on so I would like to know how feasible it is. Since I want the items to have extremely high unbreaking anyways it doesn't exactly matter if the damage gets updated too often
