The only other thing I could think of would be a spot for something like http://www.digikey.com/product-detail/en/AD594AQ/AD594AQ-ND/612068 and jumpers to connect its 10mv/degC output into the input of one of the ADCs. Then if desired, the person building the board could populate in those ICs and read out thermocouples. I'd put a couple spots of those if there is space. Ideally they would be by the top edge of the card so the thermocouple can connect close by.
