can i re-format an existing luks partition (as the same /dev/sda[x] and simply re-copy an fsarchive operating system backup straight to it without anything further required ?
There's an offline cryptsetup-reencrypt tool in cryptsetup 1.5.0 and later. It's really offline so the device needs to umnouted before reencrypting.
Also you should consider shrinking the filesystem residing on the luks device (and after that also the device) before actual reencryption. It makes reencryption sector-by-sector no matter if it is used by filessytem or not.
Also there are some fixes ready for reencryption tool on the way so you may be also interested waiting for 1.6.3 release in coming weeks.
