Moving heater to make room for sub/box

I have an 03 SAN and I'm thinking about yanking the heater to make room for a sub box like I have seen a few others do on here under the helm. Cut out the hump, re-glass, etc to make room. My question revolves around moving the heater core. At first I was tempted just to get rid of it altogether, but then I thought hey, why can't I just relocate it?? I could do without the vent under the dash, but couldnt I mount it somewhere near the back of the boat and just have the one outlet with the flexible hose piece into the passenger compartment? I was thinking of having the outlet on the starboard side by the back seat, just kind of tucked away back in that space.Any thoughts? Im going to post over on Planet nautique as well, but I figured somebody on here has moved their heater core....what do you think?
