If that skeleton you’re mentioning is actually able to use the same items as the basic characters, it’s a new character, therefore it’s most probably a lot of work.
You can download the Developer Pack from over there ^
A skeleton character would need to fit all the categories from the pack. That’s easier said than done. 🙂
Unless you find an artist interested in creating that whole new set for ePic, inserting the skeleton in postwork is way easier on a case by case basis.
Lemme see what I can do… ^_^
