I guess it all depends on what is the priority for the IAC. Are they willing to sacrifice the reliability, popularity and adaptability of the jet for the cheaper option of a turboprop. No doubt a Saab 2000 or Q400 will have lower operating costs but I'm not sure how they will handle the occassions when four S92 loads need to be moved on one flight. I would rather not be hanging around in SCS for an additional aircraft to arrive from ABZ, especially with a connecting flight home.
