Don't freak out, I'm bored and just thinking outloud to see why it may, or may not work, throwing things against the wall to see what sticks if you will. So I see RV builds, well that won't work on my BTLE, the stack will be in the way of the three door IMO. So what's so crazy about a double reverse flow? More mass to heat up, plenty of smoke still? Should be plenty of room for two reverse plates? I don't know, honestly, just a crazy idea rattling around in my head.
