recast the movie to try make it a hit
In the Banks role have Cameron Diaz back to give it abit of A list glitz and connect directly to the previous 2 hit films - as has happened with all the recent belated 'legacy' sequels Star Wars, Terminator etc (no need for Drew or Liu but they could cameo)
Then instead of Twilight you get some really popular ridiculously hot actress in her late 20s/early 30s who is also a big name (ScarJo, MRobbie - basically whoever would take a gamble on it).
plus maybe get a recent Bond or MI girl (Olga whatshername, the Spectre one) so could have the 007/MI connection. Aladdin girl can stay and play the new recruit the other 2 they have to train up
Then for the director : someone who has done these kind of action movies before who would agree (probably one who maybe hasn't done much of late/not so in demand so might do it for the $s/profile e.g. a previous 007 director? John Woo? hell maybe even bring back McG!)
