So this is a bike for my wife. She is 5ft3in. We need a bike that can handle light gravel, light trail, and is fast in the city. With the ability to have fenders and racks. Road tires or fatty tires. So that narrows it down to touring/cyclocross. Because of her height it narrows it even more down as a lot of cyclocross/touring don't make her size or are more men's.. She is a inexperienced rider who has fallen off her comfort Raleigh hybrid 700cc wheeled bike.

Because of that as well I can only find this bike... http://salsacycles.com/index.php/bikes/vaya_3

The Vaya 3 makes sense because it would seem my wife would be more comfortable lower to the ground with 26" wheels. And give her more confidence. She however is afraid of using drop bars. So I am trying to figure out if I can get a moustache bar or similar to a cruiserish or flat bar... However I don't know how to convert bar end shifters and don't know if you even can? Because bar end shifters are out. I doubt it'll work for my wife at all.

So if anyone can tell me if diff bars and shifter mechanisms are available for this bike.
Of course I am open to more suggestions of bikes as well hit me please.
