The Longbow Hellfire 2 missile is expected to have the same range capability as AGM-114F, with a minimum range of 500 m and maximum range of 9 km.
Well, not 70,000 feet but it could lower altitude then fire. If not they could always go with JDAM GBU-29 250-lb MK-81.
Hanging any ordnance on the GH would require redesign, not only on the wings, but avionics, control systems, possibly landing gear, etc. That would add a nice chunk of change to each airframe.
