If my memory is correct there is one incidence peg on the boom as well as the holes for the wing tube and the recess for the retract cylinder.Unless Feibao have done a major re-design I would think you could get away with re-positioning the incidence peg in the boom or fitting the incidence peg in the wing root and making a new hole to suit in the boom and glueing in a carbon tube to suit the incidence peg. Even if it's not very neat it will be covered up when the wing is fitted.
