I'm probably going to modify the pattern as well. I'm planning on making a shitload (pardon my language) of plushies for the con, so they're bound to have variations. E.g. I don't think Sephiroth should have the same pattern as Misa; lol!! 
So true! Modifying is hard, but satifying work. I understand why people are so reluctant to put free patterns on the internet.Good luck with you butt load of plushies!!
