Well, that's the idea and since ogres are one of the worst teams anyway, adding something singular cannot ruin them. I'm not sure what that Big guy would be though. Something with strength 6, to make him stand out as a Big guy. Maybe a gorger, with Claws and Wild Animal, or a greyback or maybe a (tiny) slave giant with Really Stupid

Just tossing this ridiculous idea out there, if someone wants to make something out of it.
