Disney would immediately lawyer up if the shoe was on the other foot. What's good for the goose is good for the gander. Disney can't have it both ways!
A company like Disney doesn't really ever lawyer up, because that would imply that they are ever lawyered down. I have to agree with scott_s on this. You're in a bad enough situation pitting the lawyer you can afford against Disney's team. If you try and face them by yourself, you're going to get screwed.
