SmokingJoe, it wouldn't be cheap but you could always try calling Weber and saying you horribly damaged your beloved 2005, 2008 or 2013 grill you got from Crate & Barrel and can you buy a replacement kettle and lid? Just use the donor Performer chassis of your choice.
The relevant Grass Green part #s:
kettle: 90717
lid: 61493
(ereplacements.com won't have them anymore, but that doesn't mean Weber doesn't have a few pairs stashed away)
You could also try including a short line in your signature here. Maybe someone who has one will see it and decide to make an offer.
