I planned on it. I was actually thinking of having the extra gear be on the bottom end, though. That way, if the worst were to happen, it would just go over the small gear, not into the spokes, and it'll keep the cable/derailer from getting pulled on if she were to shift into the non-existent gear. I think that'll be nice with the bar ends too because then you'll never have to have to use the shifter in the farthest/more difficult position(not that it's at all difficult, but just as a matter of comparison).
