For starters, the game gives ample ammunition for him shill his PC x PC ship, by having the boy and girl of Swsh get the legends, and save the world together, with no Lillie figure to shove in the way.
Even Rose's motivation can easily be fixed by just making adjustments on the circumstances. Places more emphasis on the energy shortage plot, and even make Leon a fraud who relies on Dynamax to stay relevant. Wouldn't be the first time a champion character was made somewhat antagonistic. Just look at Lance, or even several gym leaders.
