If you wait, you'd be able to sub in the new Tiagra 10 speed hydraulic brifters/brakes, but even that won't be inexpensive. If you don't want to wait, you'd have to convert everything to 11 speed (105 or Ultegra level).
So it's physically possible, but why bother? If your Sirrus fits you correctly now, it will -- even with a silly-short stem -- not fit you properly with drop bars. If you want drop bars, buy a bike designed for them.
Agreed. A conversion is more trouble than its worth. You can't fix the geometry with stem and a drop bar change so as I advised OP, if he wants a drop bar bike, then he should buy a drop bar bike. Few hassles to get the bike he wants.
