Well, they'll pull cable, but unless you've got popeye like forearms, you're going to have a hard time stopping your bike. V-Brake leavers pull twice as much cable half as hard, so you'll feel kind of like your brakes just hit a brick wall, and aren't really stopping you.
I've had them set up with dual pivot calipers and I thought they worked well, although these levers provided less mechanical advantage due to the extra cable pull. The plus side was that they provided a solid lever action (not mushy) and you were able to position the pads a bit further away from the rim.
I agree with road fix, It depends. Some of those integrated hybrid type of brake levers can work with both types of brakes. Did you check in the internet if that model in specific worked with regular calipers? I believe some of them do work fine with calipers. Other brands use a pin inside that can be moved to adjust the pull tension to short, so they could be used with regular caliper brakes (tektro and cane creek i believe)
Campagnolo does a brifter for flatbars 10 sp compatible with calipers also. No idea about v-brakes but probably it works also. Worse case scenario u can use a travel agent to correct the problem.
