+1 IMHO, you won't get a satisfactory location for good leverage and fit. If it must be an Italia build, then you will have to suffer through the 300 mile event.
I recommend a pair of Tektro R341 aero levers. They are designed for smaller hands. The older R200a/100a version looks better, resembling Campy ergos. But they are no longer in production.
Perhaps Cane Creek still markets this small-handed version of their SCR5.
