It's not likely going to work. OS X, like the BSDs and to a lesser degree, Windows, have userland and kernel are developed in tandem. It's not expected, that say, the kernel from OpenBSD 5.7 will work on a OpenBSD 4.9 system (or ntoskrnl.exe from 8.1 on XP) due to changes in system calls and structures. Something like Linux can (as long as you brought modules) because Linux and the userland are decoupled and Linux has a lenient backwards compatibility policy.
