That sounds fairly reasonable, though I have not tried that approach and am
not sure whether it will work as expected.  You will likely need to to
manually arrange for the CD image to be mounted in the installer, so that it
can find the files.  You would do this by switching to virtual console #2,
mounting the system on a scratch mount point, then loop-mounting the ISO on
/cdrom, and resuming the install on console #1.

Let us know how it goes.
