I stand to be corrected, but I believe Funchal ATC don't routinely allow landings on Runway 23 (approaching the 'elevated' end). I assume this is risk based, but could be due to prevailing winds. If true, and Leeds did something similar, it would surely place operational constraints on the airport.

I don't think anyone denies it could be done. But it would be very expensive and very difficult if not impossible to justify in terms of ROI.
