This will work. Just take care that the new partition scheme does fit
the current fstab. But it is not big deal to adjust the fstab if you
decide for a different partition layout.

If you already have a Knoppix CD your scenario is good, plain and easy.
Of course you could boot your existing Fedora system into runlevel 1 and
do the same copying from the running system. Then you have to care for
not copying /proc and some not so important data will maybe fail to be
copied.

http://www.partimage.org/ may be an alternate.

"cp -a" is enough; of course you could work with tar too, with syntax
like this:

(tar cplf - --atime-preserve --same-owner
--exclude=/proc/*,/home/*,/var/spool/mail/*,/tmp/* /) | (tar xplf -
--atime-preserve --same-owner -C /mnt/root)
