"Undo" biwiring?

If I have speakers with bi-wire terminals and only want to use single wire cables, is there any reason I can't desolder the wires from the low frequency posts and solder them to the high frequency posts or vice versa? Seems to make a lot more sense then adding expensive jumpers (which have made a difference in my experience), yet I have never seen this done or suggested. I would also need one less set of binding posts if I wanted to upgrade.
