Kewl. FWIW: we already have the ability to migrate processes in the ORTE code. You can tell the system to try and restart the process in its existing location N number of times before requesting relocation. Of course, if a node fails, then we automatically relocate the procs to other nodes.
The relocation algorithm (i.e., where to put the relocating process) is in the "resilient" mapper component (see orte/mca/rmaps/resilient). It tries to ensure that we don't relocate the proc to an inappropriate place. I can provide more details if you like.
