Don't expect to be able to get your flat bar controls onto a standard drop bar w/o modification.
Even if you get a 22.2 mm drop bar it's not guaranteed that you'll get the controls past the bends w/o undue force.
Why not try a pair of drop bar ends?

Install is real easy.
Will do what you ask for.
If you like it, and develop a severe allergy against the bolt-on pieces, you can research a permanent solution at your leisure.
Best post here. yep, mountain bike levers will not fit on drop bars - different diameter.
Most road brake levers don't work with mountain bike brakes - I'm not familiar with the pull ratio with hydralics though.
Those bolt on drops look like they could be the ticket. A bolt on triathalong aero bar would work too if you like the aero position.
No you don't need a different stem to go between flat bar and drops. you may prefer that, but OEM manufacturers use the same stem on bike that are sold in both configurations.
(when you are on top of the drops, you want them about the same distance away as the flat bars, when you are in the drops, your reach increases proportionately).
