Here are my dubs, OP. That thing happens to me sometimes
Starter (I think Decidueye or Incineroar. This is the hard part. Choose whatever you like the most. I think Decidueye makes more sense, as Hau would have Popplio and Kukui would have Incineroar, but I like Incineroar more.)
Solgaleo
Eeveelution (egg you get), if possible make it contrast with Hau's. If he gets Flareon get Vaporeon, etc.)
Aerodactyl (gift in Seafolk Village)
Silvally/Porygon-Z (Gifts in Aether Foundation)
A. Exeggutor (it attacks you right when you go to Exeggutor island)
As you can see they use the sams formula as Red's team. Only Pokemon you get in gifts, or interactable Pokemon. I think that would be his team.
