I can totally see how it would be easy to get carried away with modding!
I love modding the Kick, if you want the full hex driver you can get one here that is 3d printed in metal. https://www.shapeways.com/product/9BPFW6924/leatherman-wave-charge-rebar-1-4-quot-bit-driver?li=marketplace&optionId=155574352 If you fit a diamond file in yours keep us posted! All the files I have used so far can't clear the plier head because the teeth make it slightly thicker than the knife blade, but don't make me stop you from trying!
Sweet! I'll eventually give that a go on my recently acquired Kick, but with one minor difference: the scissors will replace one of the screwdrivers.
