Hacking Anyway to change which Mii a game's saved data is associated with?

[JSny6]

Using Metroid Prime Trilogy via USBLoaderGX, but I realized the Mii I selected to put the save data on is my brother's mii and not mine (they look similar!) I've already completed the first metroid prime and am 40% into the second one.

Any way I could just extract the data and change which mii it is associated with? SavegameManager doesn't seem to have such an option...

Didn't realize I posted twice, my bad!
