ProtoDAC TDA1387 X8 project

I received a question regarding power. 

ProtoDAC receives 5VDC power from the Raspberry Pi GPIO by default. 

It is possible to have ProtoDAC powered from a separate supply by removing pins 2 and 4 from the GPIO header for ProtoDAC. This is essentially irreversible once the header is soldered in place. Power would then be applied to the 5V and GND pads between the RCA jacks.

Or perhaps do a little surgery on a so-called stacking header (example) for a reversible solution?
