I think installing using installer, even if you have to hack it a
little, is much easier and faster than that. And allows for easy
partitioning, setting up for example software RAID etc. And installer
will take care of proper selinux labeling, partition alignment etc.

Installing normally on a virtual machine of the same disk size as target
system and then copying disk image over network using LiveCD is another
possible approach, also simpler than yours.
