Sort of but again no. He problem is if you have really wide coded stripes your I/O costs to reconstruct after a failure will be astronomical, and the probability of one failure increases with the number of participating devices. Besides you could not reshape the stripe in response to anticipated failures without reading and writing the whole thing, in which case you'd be better off in terms of I/O costs just evacuating the device in question.
