C27
Sorry for going off at a bit of a tangent but wouldn't the aquisition of a dozen or so C27's help with the helicopter shortfall? On some ops in the field it's either a C130 or a CH47 that has to carry out the operation. The Americans have recognised the need for a small-medium transport aircraft.
I wouldn't replace helicopters with them but augment airlift in general. The reality check is the cost of another type I guess.
