Well it depends on the movie, really. Can't do Team 7 movie unless you acknowledge that the movie is a complete madeup. I know movies are non-canon, but you can't really break characters until you acknowledge it as an spinoff or alternative spin on it. The only condition to be made is have Sasuke come back to Konoha in the manga before the movie release. So, that won't work unless you could do a reason for it to happen, much like bond movie.
Yeah exactly cause if they were to focus the next movie on team 7 interactions then it should happen around after the fourth ninja war arc when they beat Madara in the anime. Each of the shippuden movies always come out right after a certain event happens from the series in the anime....
Shippuden movie 1: after the two year skip
Bonds: Naruto's 4th tail transformation
Will of fire: Asuma's death and Rasen shuriken
The Lost Tower: Minato revealed to be Naruto's father
Blood Prison: Naruto's Sage mode training
RTN: project tsuki no me revealed and Naruto's relationship Kurama changed after their fight
So it would make sense that they would make the movie (if they made it for team 7) to be around the final arc in the anime series lol
