I bought a new Cannondale tandem that had Ultegra shifters, Truvativ Elita cranks and a 105 front derailleur. The problem was the amount of cable travel from the Ultegra shifters limited the amount the d could travel. If I moved it to where if would shift down to the granny, it didn't pull enough cable to shift up onto the big ring.
A shifter that allows more derailleur travel will be better at forcing the chain off the middle ring and down to the granny. A chain catcher or such may help with dropping the chain, but as I understand the OP thats not the problem yet.
