Flat bar to drop bar conversion

Guy at work was asking me if you could convert the Boardman Hydrid Comp from flat to drop bar easily. He likes the idea of a disc brake for winter use but didn't want to spend too much as well as we might be having a bike to work scheme soon so Halfords might be our choice. I think Sora/Tiagra shifters(9 speed) are ok for the shifting but what about the brakes? They're Avid BB5 mechanical discs, would they work with the shifters? Obviously bars are easy but would he need a longer stem as I assume the top tube on the Boardman is shorter than a normal road bike?
