Looking at the Japan All Time records, it would be very, very hard:

Frozen is the only film which has made that sort of dent in the last decade. It still couldn't dethrone Titanic, much less Spirited Away. It's really telling when you look at the Harry Potter numbers too, where it's a straight decline from the first film all the way downwards. 1>2>3>4>[8]>5>6>7. When the hype boost for the grand finale of the franchise couldn't even boost it above the 4th film, you know the market is stagnated as fuck. Miyazaki's final film The Wind Rises "only" collected 11.6 billion yen in 2013 too. So Miyazaki can't beat Miyazaki, Cameron can't beat Cameron. It's bad all round.
