Surely they could cut out all the filler entirely. They're just under 150 episodes behind. If they cut out the ~52 episodes of filler we're going to total, they'll still be 100 episodes behind. Even throwing in another filler year to cut there are still 50 episodes. And let's face it, I doubt there'll be any other episode skipping or merging (have they even shortened episode lengths yet? Seems like they've kept the same timing to me so far), except possibly episode 26 since that's a full episode.
Even if they're paranoid, they could leave the best half of the filler or something. Keep all the funny episodes, keep the best arcs, etc.
It'll never happen if they reckon the fillers will fare well on American TV though.
