From what I understand, the MESA hardware essentially already offloads most of the important real time stuff into the FPGAs. Remember, you can, in addition to quadrature counters, PSI ports etc, fabricate an entire micro-processor inside an FPGA.
One way to look at what the Mesa hardware does is that it runs LinuxCNCs "Base Thread" in hardware, so only the (normally 1 KHz) "Servo Thread" is needed.
BTW Mesa Ethernet cards always have at least 1 CPU embedded in the FPGA fabric (for Ethernet communications), and may have additional CPUs for SSerial device communications or a 32 BIT DSP embedded for resolver interfaces.
