Linking Fighting/Shooting skills to a different Attribute

[javadragon]

I tried to search the forums for this answer, but I have not found a thread that matches what I am trying to do. So, if there already is a post that you are aware of for this, please link it here.

Goal:
I am creating an Edge called Smart Fighter. This edge allows the character to link their Fighting and Shooting skills to their Smarts, rather than Agility. Is this possible?

I thought about making new skills and not allowing the current ones, but I am not sure how I would link the weapons up to this new skill for their stat windows.

Other than that I think the only other way to do this would be to "refund" (increase skill points to offset extra cost for low Agility score when buying into these skills) buy costs back to the character.
