+1 to everything posted above

I did the conversion on my 7.7fx. Ultegra brifters, Ultegra FD, FSA bar, Jag rocket adjusters, Shimano R550 cantis, f/r cable hangers plus tape. Came out nice...but adds up with these bits. It was one of those "not cheap" conversions.

Rode it that way for a little while, then converted back to original and sold the bike. Still have all the components boxed up.

You could convert to drops for ~$200 in parts + labor, if you went with Shimano BS79 bar end shifters and Tektro RL520 brake levers so you could use your current v-brakes. You'd still need bars, tape, inline barrel adjusters, and maybe a stem. Not cheap, but not exactly expensive.
