Matt,
A through scupper might be tough however My boat is plumbed with the pump inside the boat. The intake hose simply threads onto a Washdown fitting. Works very well. No priming, minimal setup, and very sleek.
But if you dont want a hole in the bottom of your boat we could figure something out. Would probably be similar to how the Hobie tank is plumbed. Only problem is the location of the scuppers on the Trident. Ill start drawing out some ideas and playing around with it.
Oh an I am totally taking the full credit for the Flushmount set up. He copied me.
