Not really. The movie was explicitely stated to be basically "chapter 699.5". Someone could create a timeline which shows the events shortly prior to and after the first timeskip and include the current filler arc. That wouldn't make the filler arc any more canon, it would just show when it happens.

Long story short: A timeline doesn't make things canon. References in the manga do.
