It should take place sometime between Fishman Island and Punk Hazard (sometime after One Piece Film: Z to be more precise). I mean movie 5 took place after 4, and 7 takes place after 6.

Also, I don't think the straw hats will be much weaker than they were in Dressrosa. Luffy already knew Gear 4 during the timeskip, and we haven't seen the full extent of any of the straw hats abilities yet. We haven't really seen any of the straw hats pushed to their absolute limits yet, so even if they were considerably weaker it wouldn't be so bad if some of them get decent fights.
