Mike,
That's cold brother. Just for that I'm gonna follow you and poach from your net.
If you do have the blood, then I'd recommend you freeze it in milk jugs. Take those jugs out with you and use it as chum. I'm not too worried about GWS at midnight as they're suppose to be sight feeders. But there's nothing like getting the creeps when something big bumps into you or that same something makes a huge bioluminescence vortex next to you.
Todd,
Got room on your boat for a diver?
