By way of explanation, there is a bug in the SAM3X microcontroller chip. If you enable the ADC input to read the on-chip temperature sensor, port PB27 no longer works.
In the build of RepRapFirmware for Arduino Due + RADDS, we disable the CPU temperature monitoring facility for this reason.
Are you planning to support RepRapFirmware on your board too? If the pinout of your shield is the same as RADDS, then the RADDS build of RepRapFirmware may work on it as-is.

The Pins_RADDS file defines two serial ports, of which the first is the USB port. So one of the real serial ports should work already. To get the other one working you would need to increase NUM_SERIAL_CHANNELS to 3 and define SERIAL_AUX2_DEVICE as Serial2.
AFAIK dcnewman hasn't done much work on his fork since I integrated it into mine, but I could be wrong.

To use an ESP8266 connected via serial only, ESPRINTER is the way to go. The ESP8266 support in RRF assumes a high speed SPI interface between the ESP8266 and the main processor.

If you want to try that, I suggest you look at the Duet WiFi schematic. You'll also need to make a few firmware changes, because although I prototyped the WiFi interface on a hacked Duet 085 two years ago, all the subsequent development has been done using the SAM4E processor. So some changes may be needed. Also the SPI bus on the Duet WiFi is dedicated to the ESP and I doubt that sharing it with the SD card or anything else would work well because of the high speed.
