Look, we're not going to implement anything that overwrites existing resources as-is unless there's extenuating circumstances, such as with heads and their limited number of slots viewable in the toolset/character creation. We can consider renaming the models/icons but that really is a pain and we're only going to do that if it's worth the effort.
Also, we JUST released a crapload of new content yesterday. We're not going to update the hak for a while now. We're all beat from working on it for the last month and a half. Give us a breather before you start asking for more stuff, okay?
