Minimum chainring with Campy front derailleur -- MTB crankset?

[danield]

Can I run an MTB crankset (e.g. FSA 42-27 double, or 44-30 if i can find one) on my Campagnolo Veloce equipped cross bike, using the normal Veloce double front derailleur, assuming I'm within the proper parameters of chain capacity for the derailleurs (I'd be using a medium cage rear derailleur)? I've seen a "minimum chainring" size value of 34t published in some of the Campy documents, but it seems to me it should work.

I'm sure this has been asked and answered but I can't seem to find it in searching the forums or google for that matter.

TIA!
