I imagine it would work to some degree. My concern is since the source end is supposed to be the voltage source, I may be back feeding some diodes or circuit elements in a way they were not designed for, and degrade the sginal, or worse deteriorate the circuit. I'm not sure if this would happen though, since it seems to me a video signal is an AC sort of signal, so the voltage is changing direction anyway.

I am going to post this question somewhere where more EE types might see it, and will post back here if I get an answer.
