Sorry man, it won't happen. Routes aren't profitable enough. If anywhere MIA may see them first, but again I doubt it. However there was some speculation recently that a F100 would replace an ATR 72 on MIA-NAS. I doubt that will occur as the Fokker doesn't visit MIA and a separate support operation would have to be established or the plane would have to be rotated to Dallas often for service.
Speaking of being up to your neck in ATRs, how about those lovely Gulfstream dba TWConnection Beechs?
