I've not tried it, but it would be worth trying morphs for SP3. I've used V3 morphs on Aiko too -- not the standard sets, which are built-in for Aiko instead of being INJ morphs, but add-on packages. The different size and starting shapes can be a problem, and not every morph will work well at a full 1.000 Also. there's the Kioki package for Aiko.
