Let me elaborate on Cpt.Frostbite's question.
At this stage we have reached beta version 7 of the MH60s during our internal beta testing. As a result most of our efforts have been concetrated in completing this addon.
As a consequence we have given little thought as to the direction of our HH-60Gs from the USAF. However, the texturing of these units has been set up in such a way (by master texturer Ebud) so that we can easily apply camo schemes with minimal effort. What this means is that conceptually, it would be relatively easily for us to simply play with the brightness levels of the MH60 all black textures to come up with a Gunship grey variant. So there is a good chance that this is an easy thing to accomplish.
However, the HH-60G project, although based on the pioneering work we are doing with our MH60s will require some modifcation. For a start we will need to create a new radar model (as HH60s have them installed on their chin) and this means new LODS and some new textures. I would also like to add something to the helos that differentiates them from other H-60s...like changing their weapon loadout for example. However this remains up in the air.
Like I said, we haven't exactly thought through the design issues yet as we are working diligently at completing the MH60s.
