I'll bet the first thing she'll want is a relocation of the shifters. Nothing wrong with downtube shifters with drop bars, esp. if you're accustomed to them. But we tried a FBRB (flat bar road bike) setup for my wife a while back, retaining the DT shifters. I just didn't work out; we're reverting to a drop bar. There's another recent thread featuring a bike with this type of symmetric shifter boss, and a bolt-on adapter for extending cable housing upward. In that case, it was for stem shifters, but it could just as easily be used for bar-clamp or bar-end shifters.

In any event, save the original parts, in case you opt to sell it in the future.
