Boxed wing tiltrotor design

ArduPlane VTOL Plane
1

I am about to start building a tiltrotor VTOL plane and had the idea of a boxed wing design. The motors will be mounted by to the fuselage and be able to tilt for forward flight.

does anyone knows if its possible with ArduPilot? or have any experience in building a boxed wing design.

Can you share a sketch or image?
Ardupilot supports a lot of types of VTOL. Tail-sitter VTOLs have opened up lot of configuration.
