Try to project face's boundary edges or wires to the target face,then use th projected edges or wires and the target face to build face,or split the target face

yes. so i project face's boundary edges to target face.

but i face another problem. i get discontinuous wire , because i use boundary edges.

problem is below pictures :

Use the discontinuous wire and target face's wire to build closed wire
