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.
