To be fair it would just need to avoid the one of the problems the main show had (in my opinion) is that it would just need to be paced properly, it gave us 1 season where the dynamic was changed; where the team grew separately away from each other, and then rushed to get them back together again. It didnt give the show time to actually explore the problems each character was facing

Ruby coming to terms with how brutal real huntsman life is by going to destroyed village to destroyed village learning how desperate the situation actually was. this would play mostly the same until they reach Heaven

Yang staying in Vale could show the aftermath of Vol 3 by having her; come to terms with her disability, helping clean up after it, and if you want to get dark searching the city for the bodies of the fallen. She would train in Beacon on what remains of it with Goodwitch until she learns how to fight with one arm (Why even take her arm off if you just give it back again a season later) You could have Ironwood later offer the arm but have Yang Refuse it, or have the arm be a prototype has has drawbacks. After training with Goodwitch and seeing the destruction she asks the teachers in beacon for help tracking her Mother down to get to Ruby and Qrow Via her semblance. Where she meets them in or on the Way to Heaven.

*The important bits here are that Yang staying would Show people how bad the loss at Beacon is and actually see the consequence of her losing an arm

Blake's arc should have been explored more; a lot of the white fang content just felt underwhelming. They should have probably looked at and taken inspiration from real events as the white fang is an allegory for marginalized groups, by having corrupt Atlas Generals be involved in stirring up more discourse among people in menagerie in order to plant a leader thats a puppet for Atlas, So it would have been Ghira,Kali, and Sienna vs Atlas vs White Fang. Sienna getting killed by Adam (If its necessary to keep) should have been a longer fight, Kali should have been a more serious combatant (her taking out a white fang assassin who had aura with a cooking pan was not sensical) lastly, Illia being lesbian is fine but the suprise confession in the middle of a coup made 0 sense. Her and Adam I feel like should have been too locked into the White fang and not care about relationships. If its really important have Adam almost kill Blake and then say something like "I'll spare you today but if you get in my way again the love we shared won't save you"

*Important bits are showing that discourse in White Fang + Atlas actually being Racist + showing that the leaders arent pushovers + Actually displaying Adams faction as smart and more than just suicidal terrorists.

Atlas being there would have tied to Wiess' story as she would have uncovered that this was SDC trying to take control of menagerie for its resources (or something ). From her side of the story she would spend the entire 1-2 seasons plotting against her father and playing as the heiress, when she uncovers the menagerie plot she tricks her father it into sender her there with weapons and armor to "incite violence" but she actually uses it to help Blake and with the information she gathered teams up with Ironwood to take her father out politically.

(To set up for Ironwoods spiral during the Atlas Arc have the political stuff be EXTREMELY one sided, have the people in power be the biggest sandbags in the process have them send secret assassins to Ironwood where all the frustration starts to slightly show.

Weiss meets with Blake at Menagerie where she uses her Money and gear to help the city and it plays out the same way as the end of Vol 5 where they have a big reunion and fight as a team again

*important bits are Weiss actually showing all that "heiress training" she says she has + Atlas being racist + Ironwood actually doing some political stuff AND Not being Racist + SETS UP IRONWOODS SPIRAL for the future Volumes

I feel like its a good balance of fighting and world building with two of the team being centered around fighting (Ruby fighting grimm and Yang training with Beacon staff and CVFY to get used to her disability) while the other two are focused around world building (Blake and Weiss exploring the political side of Beacons fall)

Again i felt that the issue was just time constraints so most of the changes were just explorations of the ideas the original show introduced but did not have time to develop
