Locke to Gogo?

Hey guys! I'm new here and thought this would be the PERFECT place to figure this out... I'm in need of some help... I have a character replacing Locke. He's a character of my own creation and I want him to be, for lack of a better term, a bag of awesome! I keep thinking about giving him different abilities but none of them are, imo, suited enough for him, though at the same time they ALL are. I also can't keep steal off him bcuz there's a time where he NEEDS it in south Figaro... I was wandering if there was a way to give him Gogo's ability to use other abilities in the status menu. If anyone has any idea how to make Locke be able to select the skills for his skill menu PLEASE help me do it. I would be greatly appreciated of it. This is the LAST thing I need for my edit of the game... Thanx for any help ahead of time!
