The problem is, WorldScape is a multi-version server, we can add any version of RuneScape at any time, so if we wanted to add those 2 capes we would have to make the item ID outrageously high. Then we would have to Add them into the client for each client version we have, so currently both 508 and 317. Everytime we add a custom we would have to make sure each player re-downloads the cache because we would be correctly adding them into the cache. It's a lot more work then we need. I don't foresee any custom items.
