It should work. Bear in mind that you'll need to set the front shifter to friction, since there's apparently a difference in throw between the indexed road derailleurs and the MTB derailleurs, they don't index the same. I think these are the same as what I'm using, and they work well.

I have been monitoring Suntour barcons, but it's a little more pricier than I want to spend. Ideally I might go the route of replicating the current setup on my Salsa Vaya by using barcon for FD, and brifter for Rear.
