After crunching sme numbers I can see that the 200 can get tight in the Medivac Ops, especially on a long leg (remote opserations)with weather and combined with added medical requirements.
The B350 would be nice for you guys but then you would run into problems with night approaches into strips with no navaids. (Over 5700kg).
Budgets being budgets and suitable aircraft being another problem I suppose, at this time anyway, there is no easy, and not excessively expensive, answer.
Pity, because there certainly is a benefit to flying two crew.
Enlightening thread all the same.
