The wing chord would need to be extended, and likely the wing moved aft. Alternatively, the engine could be moved forward, or some combination of the three. I think that a parasol would look better designed from scratch. YMMV.
It’s called add the turtle deck and tail shape to an existing parasol. Looks with no need to redesign. It’s how I would build an Acey Duecy. That or a Acrosport 2 shape added. If I could add a swept back wing to make a RWD8 looker but that is design. Swept back on the Acrosport fuselage would be great.
