That might be a problem since the MAX6675 is SPI and NOT I1C. It uses a 3 wire interface - MISO, SCK, and CS to communicate and not SDL / SDA to an address like I2C...
You can wire common MISO and SCK to all the max parts you are using but you do need an individual CS (aka ss) to each board from a unique GPIO pin. Yay!!
