Changing the wires wouldnt be that tricky, but you will probably need the special flux and solder if you remove the wires right from the tabs on the cells (could always cheat and just replace the wires just after the exit the pack). Shortening the balance tap wires would be the same procedure really, but it would be just as easy to bundle them up a bit with a ziptie rather than mess around shortening them.
