The answer, IMHO, is "seeded" FAA crews into CH47, AH, Wildcat (Green) and Puma 2 units - perhaps as constituted flights, such that a TAG of suitably qualified (and motivated) aviators with a broad spectrum of platforms and capabilities can deploy in the appropriate force mix.
I think AOC 3Gp/FOMA and the JFH may've put paid to that idea from the Dark Blue side.
