Sounds like a high degree of skill and perfect execution would be required.
Have read before that trying to bleed out often doesn't work as blood pressure drops and the bleeding subsides (left alone a long time may work though). Hence your idea of targeting specific blood vessels or arteries.
With the level of skill required at that point some type of active suction may make it more viable from just about anywhere. But then with all the setup you may as well find another method.
