if my guess is right, you'd have to make the moogle have the same number of bones as the save, to do that I would assume you don't have the moogle seperated in so many peices rather just 2, like the crystal and the symbol that makes up the original check mark. Should be possible by having 2 .p files, one of the lower half of the moogle and one more of the upper half. Then you could delete the old unnecessary bones, I tried doing this before but I never applied it to the save point or anything in the game.
