Founder status on the wiki is a misnomer because it's not a user right at all and can't be removed. It's simply a tag Wikia places on the user who creates the wiki with the CreateWiki form. You can always make use of the UserTags script to remove the founder tag from the user in question and then apply it to someone else.
