I don't think APV is suited to a helipad, whereas PinS would be. I very much doubt there is such a procedure, but suspect there may be future!
I agree, a single snapshot at DH of a solitary helipad without thousands of feet of lead-in lights is not ideal. The preferred LNAV (what you call PinS) is fine for approaches over flat terrain like Blacksod where the MDA would only be 50' higher than an APV (in Canada, EASA may be different). We had them in SE Asia, east coast Canada (Sable Island?), all privately commissioned by the helicopter operator and retrievable from the FMS database. They couldn't have cost much.
The financial cost of this tragedy will probably be close to 100m, so a consideration.
