How about an exportable Phoenix that replaces the US avionics with similar British systems, say the guidance system from Active Skyflash with a larger antenna and whatever other systems are needful. The British content could make acquisition rather more palatable for some countries. One could make the same offer to other countries, such as France, though I could see a joint Anlgo-French Phoenxi variant to arm FAA and Aeronavale F-14s.
