A small bizjet would be a waste of time and money for such work. But a brace of A319CJ, such as the Luftwaffe operate for VIP work, would seem reasonable. Preferably operated by the Royal Air Force and not by some PFI mercenaries.
A330 pilots can be rated to fly the A319CJ with only a very short conversion course.
