How about turning this on its head and installing a Phi directly on the mainboard, with lots of memory attached (unless it has some in-built limits, haven't checked...) and using the PCIe connection only for I/O - for which it should be fast enough. To avoid changing the architecture too much, attach the whole thing to an Atom CPU - low power, but fast enough to handle the I/O and to control the computation on the Phi.
