many people on this forum have done this but the overall concensus is that it is not worth the $ you have to put into the bike to convert it. generally, folks that have a hybrid and want drop bars have bought road bikes after selling their hybrids or buy a road bike as a 2nd bike.
you can do it if you can do the work or get the parts cheap but in the end, sometimes the bike will not be as good of a fit based on geometry. this varies greatly bc all brands use different (albeit similar) sizes.
and if you want to "try out" drop bars to see if you'd like them or not, consider getting a used older bike from craigslist. this is a great way to test the water without dumping a ton of money into a bike you may not like in the end.
hope this helps and good luck.
