I have no idea how to do this either using postfix config (but it does a 
lot, so it might be in there somewhere).

I'm not sure if this will work or not, but have you considered:

1.  Configure postfix to service mail for bad.com.
2.  Use a mail alias or virtual address to handle the rewrite.

Only issue I can see is that you're now an open relay for mail going to 
bad.com (for only those addresses defined in alias/virtual).
