Wouldn't think you could get away with two crew in a C208B. It only needs one Pilot. It does not require and second for aoc work ( VFR only )as far as I know.
I think a second pilot in that aircaft is more along the lines of safety Pilot. Our friend from Scotland would be flying a single Pilot jet which would then require and second Pilot for AOC ops.
Have a fair few hours in the C208b and I think you'd have to try hard to convince me it needed two Pilots.....it only just needs one
