The French defence minister Herve Morin recently told the French parliament that the country is quite keen to work with the UK to develop a "remotely piloted air system" that would also meet that Scavenger requirement. They appear to be also keen on buying the Reaper as a short-term solution until such a system is available. Probably can now discount everything else on that list now other than the only twin-engined offering that isn't the Talarion or American.
