It's possible to change the designs on the notes without seriously affecting existing machinery. However, changing size is a radically different issue, and just changing the length doesn't help. More to the point, you'd have to replace all the machines that don't support being reprogrammed, which is most of them, since you would need a new dollar bill as well. Again, there's no reason at all to talk about changing the size of money if there are other alternatives.
