Don't think that would fly but you may be over thinking this. Nox is not all that big. Get an Alum boat, toss on a 20 hp and enjoy the slower pace of life. It still won't take you all that long to cross the lake end to end. Even if we were allowed a 90hp you would be on the other side just as you got on plane.
I changed my prop pitch and added a fin to get some extra get up and go but it is what it is.
