Re your last on new 'Elint' platform, why not just buy 6 x U2s. They are cheap, reliable and do the job of many with only one in the aircraft, and before anyone says they are an old ac, why are the cousins from the other side of the Atlantic still updating them. I once heard someone say that the U2 does roughly 90% of what our Waddington friends do with only one person in the air.
