Just a thought, but one of the things you may run into is wing loading. The foamies tend to fly better with a wing loading of around 5oz per sq ft. Increasing the wing area a lot may take your wing loading so low that it does not fly like a plane anymore, but more like a kite.
But, as always, experimenting is the great thing about the foam planes. Doesn't cost a lot to try new things.
Let us know how it works out !
