I think a good plot would be to fast forward 10-15 years and have the world thriving and at peace, but the tribes all needing new queens or are having instability. Coral needs to retire, Sandwing lack of successors problem, Hivewings want independence again, Silkwings don't have a competent leader they can agree on. The council is failing, Leafwings are keeping Hive and Silk under their no killing tree rules, the cohabitation is failing. Skywing princesses and Icewing Princesses have come of age to challenge their mothers, Renewal is thriving and Glory is dying (of cancer or something) so the nightwings want to leave and the rainwings have a hybrid princess. Mudwings queen dies and the nobels want the younger princess not the Bigwings to rule.
Basically, the plot will be of the protagonist (all hybrid dragons) creating issues by trying to force the tribes together when it is not the solution. This allows us to return to the book structure of seperate tribes from arc one and Darkstalker which (not arguably) had THE BEST WORLDBUILDING and structure. The books end with everyone agreeing to live seperately with Queens ruling because it is the natural structure of the dragon world, because its an imperfect world, and forcing everybody to have a happy ending isn't truly a happy one.
The books could be structured as so
Book 1: Mud/Sea hybrid living in the mudwing kingdom, the Moorhen dies and the younger princess is crowned, everything is super unstable because of this and its a politics and murder mystery book which ends in news that Queen Glory has died from her illness.
Book 2: The daughter of Glory and Deathbringer has to deal with the Nightwings leaving and the Rainwings doubting she can lead, she is feeling pressure by the younger Rainwings who are ambitious and educated to take a Rainwing spouse and not her current hybrid lover (previous protag?) Book ends with Nightwings who have left declaring Fierceteeth as their Queen and news that Queen Ruby has been killed by her daughter.
Book 3: Son of Quibi and Moon has visions of death and destruction is trying to pull everyone back together and watches as he makes everything fall apart. Name him Skyfire because it would be humorous to have him named something that blinds Nightwing powers.
Book 4: Sky/Ice dragon lives between both kingdoms, Prince Cliff's lover, they flee to the ice kingdom and Snowfall is killed by her daughter, they flee back to the sky kingdom. This book is a tragedy.
Book 5: Leaf/Silk/Hive hybrid with no powers of any tribe, realizes that division is needed for intertribal peace and begs his lover to be the new Queen of the Silkwings. He leaves her to convince the other tribes that unity is killing them all.
Just my thoughs idk.
