I think you are over-thnking this.  Anaconda is overkill if 
all you want to do is blow images onto arbitrary hardware

So long as you are going through all this, why not just 
install to taste into a chroot with yum or RPM, rsync into a 
prepared hard drive, optionally fix up the fstab grub.conf 
settings, and run grubby or do a mkinitrd and grub 

(The transfer and bootloader fixup my be done with a minimal 
image, PXE loaded, so one does not even need a working CD/DVD/ 
USB port.  PXE has been on substantially all hardware built 
for the last decade)

That approach is portable, and works across all CentOS
