I have no experience with the TBM or PC12, (or Piper Meridian), but I suggest that in general, the design requirement for 620 M runway operations, and pressurized higer speed operation are rare in the same turboprop. If possible for any of these aircraft, I opine that you're skating on thin ice, particularly with the insurance company, and one day it's not going to work out well for you.
I have flown a Twin Otter, and Grand Caravan in and out of my 630 M grass runway, but both were light, and conditions favourable. Under some conditions, The Caravan would struggle.
I suggest that your objectives with this are very optimistic. Even if a type will meet this performance in some cases, I doubt it would be under all likely operating conditions, and you're back in that grey zone, where operations are atmospheric, and highly pilot skill dependant.
