Continue pointed bulge at root of wing forward to prop and all the way back. Enhance it outward a little so there is slanted side to top and bottom of fuselage . Put on a “V” tail, other appropriate touches, and it can be attempt to reduce RCS of propeller plane. Radar absorbent finish on propeller blades and hub (rest of plane?) , F-117 type glass and framing.
To me, picture hints at doing that.
