looking at what you have said 4x 18.2Gb raid 5 plus the new 2x 36.4Gb drives, what I would do is remove the hot spare, put in another 36,4Gb disk and create a new raid volume, keep the hot spare disk on site to use if you have a drive failure in the 18.2Gb raid set (taking in to account that you are using hot swap drives)and move your data from the 18.2Gb raidset to the 36.4Gb raidset.
note that you can not have a system partition on a dynamic disk.
