Being nude isn’t always right for me, since it has caused major problems in the Middle East before. This is why I suggest that you add a feature to all wikis that mention humans in which you can put on new clothing on them.
I fail to see how this is worthy of an actual feature. This is a thing that, if I understand this proposal correctly, would only be used on few wikis, mostly gaming wikis. If a wiki wants something like this, they can make something themselves.
