Relic change command

I would like to simply edit relic that change a command into something else. These are Thief Gloves, Fake Mustache, Coin Toss, Gem Box, & Dragoon Boots. Currently, I would like the relic to change the user's Magic command to Summon. Although this might cause a glitch with Gem-Box is equipped too. Or not, like with Dragoon Boots & Offering, where Jump got the highest priority.

I think this is simple enough for me to do, like just changing 1 or 2 commands within the relic code, from what I read here.

So I think all I have to do to change let said with Coin Toss to become a summon relic is
C2/5453: 02 (Magic)
C2/5458: 19 (Summon)

Later: It work, but.... for some reason, an error occurred that said I need MP to cast the summon. However, I do got enough MP.

One other thing to consider would be to change the text display for the menu.  Not a gamebreaking thing but if you change GP Rain to Summon it will still show up as GP Rain on the menu screen.  

What you would need to change is in C3, these are the original ones but just change the commands to whatever you changed them to and they will display correctly.

Code:
