I wouldn't try it without backing up all my data first. And if you're going to do that, you might as well just install from scratch.
Whenever I have made and restored an image, it comes back onto the drive with the exact same partition size as it had on its original partition, even if it is now living on a bigger disk.
I suppose if you could make the image the correct size for the RAID 0 array, you might find a way to make it work. Or maybe if the tools you mention allow you to manipulate partition sizes, you could just install the image onto the array, then resize it.
