More materials & textures is bad for performance and file size so what you can do to reduce that is merge textures together so you're using less materials and textures on your avatar. There's a slight art to it if you're doing it manually to save texture space and retain texture quality.
It's especially useful/important if you're frankensteining since you will delete meshes while keeping others so often times you'll have a texture that's only partially being used.
