There have been many threads on hybrid conversions but sometimes the search function isn't all it can be.
Drop bars require drop levers and you will need a v brake compatible model, travel adjusters, or a swap to cantis.
Bar end shifters or Brifters can handle the shifting duties with Brifters being far more expensive and more susceptible to being damaged and when that happens you can lose your brake and shifter in one fell swoop.
Bar end shifters are far more robust.
Obligatory pic of my converted Trek 7500...
I went the route of using cantis and bar end shifters with regular drop levers as all these parts are pretty easily serviced and spares can be obtained rather easily. With cantis you also need the proper hangars or in my case, I modified some existing hangers.
The Trek is comfortable, fast, and has been totally bombproof and I figure it has logged more than 8000 km since the initial build and it has seen some pretty severe use.
