I guess you just need to ensure you aren't trying to put too many amps through the Arduino since the traces on the PCB will have to transmit the power from the 12V input plug to the VIN pin. That is essentially what others are doing with the cloudy nights approach so it should be ok.
The advantage of going straight to the VIN on the MOS board is that part is rated for 24V 5A. I suspect the GND part of the 12V MOS circuit will be common with the GND pin that connects to the Arduino in any case.
