I keep wondering about taking apart a "typical" paddle latch by FIC, using calipers and a CAD program (or one of the 3D "scanners"), then taking the files to a metal sintering shop like Solid Concepts and have the latch made in nuclear grade Iconel. Maybe alter the lock cylinder hole to accept a Medeco rekeyable plug. Probably insanely expensive, but if someone comes in, they will be defeating the door, not the handle or lock... and the handle will not snap off or break unless someone took an angle grinder to it.
