A Trailer Boat

I am building fiber glass molds. My goal is to eliminate as much steal in the trailer frame and replace it with fiber glass. The technical questions I am pondering are how to incorporate a set of wheels into a two or three pontoon configuration. Why pontoons? My thoughts are that they will provide strength length ways while increased basement type storage in side them. Also the shape will be areo dynamic on land as well as on water (faster).
Thanks for your help and comments.
