One thing that I liked about HP/UX is that the stack grows up, which means that your stack buffer overflows tend to go into unused memory (and be easy to catch with debugging tools). Would there be any problem with making the stack grow in the opposite direction (assuming that you rebuilt everything that way)? It might even be possible to have the stack grow the normal way in executables which use the normal dynamic linker and switch to a different stack for library code.
