How would you update each characters rosters if PWT comes back? Who do you wanna see get what?

For example:
Misty: Wishiwashi, Mega Gyarados
Wulfric: Crabominable
Tate/Liza: the Meowstics
Volkner: Vikavolt, Alolan Golem
Korrina: Bewear, Pangoro

We never got to see the Gen 6/Gen 7 leaders/captains with full teams so this would be the best spot to do it
