The bigger issue is the work required to do this. Pulling a model out of the lgp's isn't complicated at all, but you'll need to converted the pieces to obj or 3ds so they're actually usable. FF7 character models are also made of separate pieces, so you'll need to reassemble them. Similarly with a model with multiple objects, but it's literally every piece (foot, hand, upper arm) so they wont be single mesh models.
