It's very very difficult to hack in real time properties after the fact. Most successful versions of this end up hacking in a virtualization layer to run the code that wasn't designed to be real time in the first place rather than trying to make that code play nice cooperatively with a real time system.

RTLinux is a good example which uses Linux to bootstrap a microkernel which then virtualizes the Linux kernel that booted it.
