Here is my opinion.
1. Save the old disks, take them out
2. add two new ones.
3. research on sofware raid, swap, and centos installs (blank disks). I.E. why
to raid/not raid swap, lvm or not, text mode vs. gui install....
Questions on this step, start a new thread.
4. Install
5. optionally attach old disks to access data or undo setup completely.

As the wind has blown on this thread, you have been explained that your initial
course of action is definitely from the BadIdeasInc.com department. Your
intentions were noble but very misguided, knowing is half the battle.
