On one hand, cas would be easier, but there's a chance people may use it for the wrong thing eg. uploading people's photos without their permission.
There's already some alpha ts4 skins that modders have made using real celebs, and though they seem to have been used respectfully (our community is pretty safe which is nice!), there's a chance they might be used badly, esp with less sfw mods. At least celebrities have lawyers/money etc, but if an ordinary person could be uploaded quicker and more easily, and someone used mods/gameplay to bully, it might get messy.
