[Request] Weapon's Own Damage Formula?

I looked everywhere for a script that can do what I want to do.

I want a custom damage formula script that gives a different formula for each weapon.

So, for example:

Wooden Sword's damage formula would be: (2 x player's attack) - (target's defense)
Iron Sword's damage formula would be: (5 x player's attack) - (target's defense)
Dragon Sword's damage formula would be: (20 x player's attack)
and so on...

If such a thing exists, please tell me.
And no, I'm not looking for Yanfly's Custom Damage Formula Script.

BUMP

Interesting idea. I might do this later tonight. It's strange though, in the sense that when players equip weapons they won't have any idea how their damage will change, since a weapon with less attack could do more damage than a weapon with more attack but a weaker formula.

Well actually, I already have a system to let the player know how much the weapon's multiplier is.
