Indeed, Dan!
Something like an A319ACJ, perhaps. True that it can only make about FL380 at MTOW and isn't as quick as the Globalame Excuse, but a much more suitable airframe, surely...
"The ACJ, a longer-range version of the A319, can fly as far as 6,000 nm/11,100 km with 12 passengers on board"
Or if that isn't enough, maybe an A320/321 long range derivative?
....and the pilots could be dual-certificated for the A330-200 tanker!
