Aki,
This is the biplane loophole! In a former Science Olympiad class plane, Chris Goins exploited an ambiguity in the biplane wingspan limit to offset the wings horizontally, increasing a 48cm wingspan limit to over 60cm. The plane was unbeatable and still holds the all time Science Olympiad record. Needless to say, the rules were rewritten the next year to close the loophole.
I am of the belief that the AMA has closed this loophole by specifying the "projected" wingspan to be less or equal to 18 inches. To me, "projected" means that one measures the shadow of the wing(s) on a surface. Thus, the wingspan of the shadow plane must meet the maximum wingspan of 18 inches. Your proposed plane would have an 18.5 inch wing(s) shadow. Of course, it is up to the judges at a particular event.
Good air,
Leo
