It could be argued that actually it is not a 'problem' but infact a huge saving in risk and R&D. Commercial Off The Shelf (COTS) or start from scratch yourself? Keep British Industry in the loop with the 'licenses' and do a bit of component swaps (engines, DAS etc) and bobs your uncle. Many will still argue that we should be with an F-15E over the Typhoon or a PC3 Orion over Nimrod MR4.
