Like Jeff Wills said, it might be worth trying, to see what happens in terms of the cage travel over the chainrings.

I had a road Cyclone front derailer that worked perfectly with an Alivio Rapidfire triple shifter and SR Apex triple crankset, sothis might also work.

I would set the cable tension with the chain on the middle ring, shifter in it's middle "2" position, with the chain on the largest rear cog, and with the chain then nearly rubbing the front derailer inner cage plate as I pedaled under power.
Then I would see how the shifting was to the other rings, and how the chain cleared the cage without rubbing in the useful gears (not including the smallest chainring and smallest cogs at the same time).

On some front and rear derailers, one can move the cable anchoring to the opposite side of the pinch bolt in order to modify the derailer's travel (actuation ratio).
