V-22 Offspirngs

I was searching for pics of the V-22 the other night when I came across some rather interesting pics of an attack version and further searching brought me to still more pics of various attack concepts (one was created by a chap who thought an Osprey would make a nice contribution to a combination of the AH-1 and A-10- but this is more like a Bell 609 rather than a V-22

In all seriousness, are there any plans for any kind of attack version of this system? I recently read that one certain company has been awarded a contract to develop a gun for it- now many years ago I remember pics of a twin barreled (under over combination) gun in a turret under the nose, is this the same weapon being discussed?
