I have a three-drive raid 0 as the boot disk in my machine. Is it possible to physically rearrange the drive order? Suppose I need/want to move drive A from slot 2 to slot 1. Would that render the array unusable?

Well I tried it and the answer is that yes, in fact, you can rearrange hard drive slices of a RAID0 in your Mac Pro and somehow or other MacOS figures it out. :-)

I just happened to re-arrange the physical tray locations of my RAID-0 array yesterday, and I too had no problems. I believe the disks are marked as being a certain slice of a set array and the controller figures it out when it goes to collect the array. Everything seems to be working normally for me... :)
