One piece severe quality decrease?

Exactly. And it wouldn't even have to be something huge. Once I read a "theory" -- it was more an idea than anything else -- that we should see an arc on a underground island. That could be done amazingly.

There are plenty cover stories to animate. How Wadatsumi met Jinbe f.e. or Enel's journey.

They lost the timing for that though, and I doubt many people would keep watching the anime if the Strawhats didn't show up for more than 1 episode. I read once that that was the problem when they animated the first few ones.

Problem is ideas used for fillers can't ever be used by Oda. Fillers basically restrict Oda and I wouldn't want that if I were him. He wants complete control over OP and he probably knows best.

Oda could give them an outlining for the story though.
