Final Smash Help

[Leggerrr]

Yeah, sorry for the repost here, but I didn't know where the question belonged.

How exactly do you swap a Final Smash with another character, if possible.

Like, I want Lucas to have the Final Smash of Peach.

So if it's possible, how do I go about doing it through Smash Attacks or BrawlBox. Thanks.
