Different studio

It would be nice to see just to have more gags with animation, but there is no way anybody will do a better job than KyoAni.

One very important thing to remember is that they produced this anime with everything they had, fully believing they'd go bankrupt after it was finished. The success the anime achieved as the result of the astounding efforts of the animators resulted in them continuing on as a studio, but their later shows looked noticeably lower budget, save for a few exceptions such as the bigger scenes in Chuunibyou and Dragon Maid.

But Nichijou was a last stand situation for them, more or less. On par with why Fire Emblem Awakening was dramatically better than everything after it since it was Intelligent Systems throwing in all their cards to make an incredible game, thinking Fire Emblem was going to end. Even Nintendo helped on the development side, where they usually publish rather than make it. Likewise, KyoAni threw absolutely everything at it, genuinely being astounding that it even got double the standard anime run in episodes with its level of animation and writing.

Any other studio would treat Nichijou as "another anime down the list" so it would have noticeably weaker animation, love and effort. And Nichijou's composer put in a ton of commitment with the soundtrack, so hearing new music would be very difficult to adjust to as well, let alone the director. I would settle on a new studio only if the same director and composer follow suit.

If KonoSuba could get Kanasaki back, I see no reason why Nichijou can't have Ishihara return. If they had a high budget studio with the right talent, I could see it coming close to the effort KyoAni made. Certainly not rival it, but for sure be next to it.
