That will work. Put your voltage DMM on the other side of the current DMM because otherwise the voltage drop in the current DMM will affect the voltage reading. You also need a resistor in series with the power source to limit the diode current to a safe value.
Your DMMs need to resolve better than 100μA and 10mV. 20μA and 20mV is better. We want to make multiple measurements between 100μA and 10mA. Most pedals run the diodes at 1mA max for soft clippers, 4mA max for hard clippers. Doing it manually takes a lot of time.
