At this point, a Dmitch trade seems pretty likely, and this gives them good future upside(Franz) and Lebron for a year.

They let Harden walk, and sign a PG in FA. Team would look like-

(PG) Franz Lebron Mobley Jarrett Allen And still an elite bench

While Orlando gets exactly the type of scorer they need, and the Lakers get Luka-friendly role players in exchange for one year of 42-year-old Lebron.
