I've checked the .cr2, and Aiko 3 doesn't appear to have the blank morph channels included to support morph injection. You can use Morph Manager to copy the blank channels from another figure. Then morph injection for those morphs will work. Aiko 3 has her morph deltas in the .cr2, in the old style of doing things, and that does make her heavier in memory use. But the full version includes an Aiko 3 which takes Stephanie Petite body morphs and conforming clothes.
