If you want to do something like that from the ground up you can
probably find all the parts in the 'rear' (Relax and Recover) package
in epel, although it is more of a backup and restore system than an
installer that knows how to deal with very different hardware.
Basically it is a set of shell scripts that use your systems own tools
to run a backup of a live system (with an assortment of options, but
tar to an NFS target is easy), plus building a bootable image (again
with several options)  to bring the replacement (or clone) up to a
point where it can restore.the backup.   It probably wouldn't be hard
to tweak what goes on the boot image.
