You know they require MTB brakes/shifters? This may be a problem since you seem to have drops.
I have no touring experience, but recently converted my flatbar hybrid to Jonesbar (keeping same brakes/shifters). Basically 5 hand (and partially body) positions change things up. It also added an aero position (compared to my flat bar), which made me a quite bit faster on straights. It also adds an upright position (similar to comfort bike). It was a big improvement regarding comfort and aero. Not sure if the improvement % is the same if you come from drops.
