I had some success by packaging from the lib or data directory -- I can't remember which. I wrote a script to help package one of the older skellingtons, but I think it was a version before skellington-11. It may still work though, as it seems the structure has stayed the same.
I'd be very interested to know if it works for you.
Oh right, you're the one person who used it last year too. haha -- well I'm happy to remind you of it again, and I'm glad to hear it works for the new Skellington. Thankyou! :)
