MAXIM31855T thermocouple chip, is there a through hole equivalent that works on the spi bus, having problems with SMD routing

I need to produce a circuit board to measure 16 temperatures from different thermocouples of types J and T, Maxim has the perfect chip, the MAX31855(T,J), the only problem is that it is surface mount and my CNC PCB router which is a Chinese 3020 hack does not like the tight tolerances required for SMD.

I was wondering if there is an equivalent through hole chip that operates on the SPI bus? I want to use an Arduino DUE and a multiplexer chip (CD74HC4067E1) to read the individual temperature chips via the chip select pins and the SPI bus. Does anyone have any thoughts on this?
