You would have to look at the approach/missed to see where the obstacles are. Public RNP AR/APCH is 0.3 RNP. RNP 0.1 do pretty well, but that is more expensive for the airline.
Couple of key factors for the turn location:
1. FROP at 500 feet
2. 30 seconds of stabilized flight before minima
3. Min 250 HAT for minima.
Theoretically, you can have a 2nm short final. (Ask WJ in Canada!) That close in, with FAS, the turns can be pretty tight, 2nm radius for 737. Perhaps only a quarter delta turn could get you in there nicely. That may get you around that tower(s) on final to RW14, not sure about RW34.
With the public RNP, you could have a 15 degree angle point at 2 miles. Up to 15 degrees is not considered a turn. I see they have a 12 degree angle, so its a tight one. That may also get you past those towers. or, move the towers!
I beleive the cost for an ILS is about $2Million per runway end.
