Multi-Weakness State

Hey everyone, I want to make a state that effects various weaknesses on different enemies. So basically I want to do something this:

Let's say Giant Frog's weakness to ice is 120%. When the player uses a skill to inflict the status, Giant Frog's weakness to ice increases to 150%. Now let's say I use the same status on Blue Jellyfish, but instead of increasing damage from ice, it will increase damage to fire. Is this possible through events or scripting?

Bump.
