The trouble I think you'll encounter is that the %post section of the 
kickstart operation is chroot-ed into the new system. You won't be 
able to see the original ISO, as far as I know.

The %pre section is *not* run in the chroot environment, but it's run 
prior to partitioning the system disk, so I don't know how you'd copy 
files unless you did all your partitioning in %pre, reserving one 
partition for your %post data.

I think what I'd do is create and install a custom rpm with the data 
files you want available during %post. Of course, that means you'll 
have to hack the repo on your USB drive, so it's not really a 
lightweight solution.
