You can extract the textures with Tinke... but I am not sure if you want me to go on... Basically, the heads, faces and bodies are all... as we say it, separated... So, I am not sure if you can get a complete model with all of its parts under different folders. EDIT: You can also refer to here to know where the textures are hidden...
The Wii version (Inazuma Eleven Strikers, JAP only, considered for EU release) has better, hi-res models, and easier to extract. Why don't you dump from it instead?
I've tried dump 3d models Inazuma Eleven DS and Wii Inazuma Eleven Strikers, but I can't use the program of Roxa's in Inazuma Eleven DS games, and I can't extract the files from the Inazuma Eleven Strikers ISO.
