There is a story around that this is because the OM requires 500 multi crew command hours for the PIC, so Bras FOs are not suitable and putting them in the right seat of the F100 also will not help them get an upgrade, therefore the only other option is external candidates. Do the "turboprop drivers from Skippers" have 500 multi crew command? If so then there is your answer.
My mate at network reckons there been hiring jet crew without 500 multi command over 5700kg from other jet carriers. Does anyone know what the unoffical minimas are for turboprop drivers for the F100 and whats involved in the interview process.
