You can try that with the R11 Installation CD. See if you can mount the flash drive to /media, and if you have enough RAM, you could also mount the R13-Install-CD.iso file asa memory disk at /mnt using
/sbin/mdconfig -a -t vnode -f <your-R13-iso-file> -u 9 ; /sbin/mount -t cd9660 /dev/md9 /mnt. You can then copy the files under /mnt to your flash drive.
I do think bsdinstall allows for using locally stored files instead of downloading via internet.
