I don't believe you even need an examiner. You just need an FAA ATP holder with the CE500 type or FAA CFI(Instructor must also be Multi-Engine instructor rated and Instrument instructor rated which most in that position are) with that type to fly with you. To sit right seat in the states in a CE500 all you need is the FAA MEL and and IR assuming that the plane is flown IFR otherwise you don't even need an IR. Then you just fill out the 8710 signed off by the left seat guy and hand it to any FSDO...jobs a good'n.
I agree though it'll probably be easier across the pond.
Good luck!
