Yes we did and using FRAM too. There is no need for a MCU in there, the 30b CPU & circuit board has decent SPI exposed (from memory, might be I2C). It should be possible to page code from the FRAM into RAM and execute it from there. It would be a long and painful path however -- there isn't much RAM.

As Marcus mentioned, there isn't much space for more code in the firmware image. This really is the limiting factor to my mind.
