ahhhh...someone is thinking outside the 'box'..or parallel to the box.
One 'could' use the PinS theory for an airport not in a respective navdatabase.
What is your agency application?

Point-in-space approach
Point-in-space approach. A type of helicopter instrument approach procedure to a missed approach point more than 2,600 feet from an associated helicopter landing area.
I consider and instrument approach in an airplane that ends in a circle to land a close cousin to a point in space approach. You fly an approach that takes you down to a higher than straight in minimum. When you break out, you are required, due to winds or traffic, to circle to a different runway that does not have an instrument approach . I have done these types of approaches at KMDW (Chicago-Midway) and KLGA (New York-LaGuardia). In both cases the landing runway is around 90 degrees difference in heading from the approach flown. Also in KSTL (St Louis) they have an approach that brings you down on a considerable offset of th runway so they can run simultaneous approaches. (The runways are too close together to have simultaneous approaches bringing both straight in.) In this case, the offset approach brings you to mins well off the runway centerline. Once you reach mins you have to aggressively get aligned because the minimums are fairly low and you have to remain on the approach to the mins regardless of when you see the runway, thus allowing the simultaneous operations. Food for thought.
Cheers

Here in FAA land the description of the PiNs approach is such that I don't believe the FAA will allow airplanes to shoot them. Part of the issue is the maximum speed. Presently in New York City they are setting up these approaches for the Wall Street and East 34th Street helipads. I have discussed this with our POI as I would like to use them for the seaplane dock on the East River, but as he pointed out, since I would not be flying a helicopter, I could use them.
The IGS approach into the old Hong Kong Airport was basically a PiNs approach, as you flew the ILS to a point in space and them maneuvered visually to land.

Approaches with visual segments
An analogy to a PISA for all categories of aircraft are instrument approaches with charted visual segments, like this one:

PinS are entirely possible for aircraft, and there are quite a few... floatplanes, 737-200 with gravel kits, seasonal runways. The oil/gas industry is a frequent user.
It is a way to design a procedure to a non-cert runway, or one that is not in a nav database.
PADU...you make sure you dont go missed there....
