Rear mech dead?

Campag chorus 10 speed rear mech decided to get caught up in the spokes yesterday.
Cage is bent, but I've seen replacements for sale online.
The main carbon part (the bit with the chorus logo) is snapped in half. Is there any way of getting hold of this part, or does the whole thing go in the bin?

If it was 1976 I'd say its repairable... But its 2013... Spare parts are listed here but it lists the body as 1 piece without a spare part number. Cage, sprokets, springs, nuts and bolts are listed but...
