How can they turn this into MI's Endgame?

Needs to make double MI7s paltry 570m

-Bring back Cavill (new flashbacks to MI6. Cavill is the most popular MI villain)

-Bring back Soloman Lane (MI5's villain is due a comeback)

-Resurrect Ilsa? (no one seemed to like her death)

-Bring back Paula Patton/MaggieQ (the hotties from MI4/3)

-Bring back Fishburne (cool actor/nice call back to one of the best: MI3)

-Bring back Thandie Newton? (a nod to MI2?.. ok maybe not..)

-Bring back Jim Phelps! (restore his legacy with the real Jim Phelps/Peter Graves via a CGI retro 60s scene with Nimoy/Paris .. And reveal MI1's Voight Jim Phelps was an imposter!)

-Kill off Luthor or Benji or both! (get some real shock value going on)

-A 007 cameo (Dalton, Brosnan, or Craig. A non speaking cameo as an unnamed agent. Obviously not Bond. but could be..)
