There's no way to really fix Revice, as the mess it ended up as was thanks to the slew of poor decisions made at nearly every turn.

Despite being a fan favorite (Myself included), Hiromi encapsulates a lot of their indecisiveness.

• He was never meant to be a part of the cast, but the actor charmed the crew enough to stay around.
• He then became the first quarter death, a role that nearly always involves them being revived X episodes later, but he came back without the ability to transform, forcing him to take a backseat as Sakura took the role of 3rd rider.
• His stay forced a major change for George. George was obviously headed towards an antagonistic role as evidenced by his actions early on and his apathy (Occasionally bordering on actual disdain) towards Hiromi. They were changed to become more of a comedic duo with George being worried for Hiromi.
• Because George's character trajectory was changed halfway through, his villainous turn in the finale was botched

Hiromi is just a microcosm of the show's problems. You then have the likes of Vice laughing in a menacing manner when he first sees Ikki's memories disappearing, but acting remorseful the next time it's brought up. Aguilera's obsession with Sakura literally appearing out of nowhere after a single minor interaction with each other. The entirety of the Over Demons controversy, and so on.

Making a minor change at the start of the series would have massive ripples throughout the rest, making "Fixing" the show pretty much impossible
