The TR is the real challenge, because they have few pokemon should take different roles depending on the situation, for example Mimikyu worked as comic relief, the tragic character, cutemon/shouldermon, and at the same time Jessie's most powerful weapon.
For G9 I would have given them a modified Revavroom that will function as a RV/Bus and TR's central of operations while chasing the protagonists for Paldea, such as indivudual pokemon, a Capsakid for James and a Tinkatuff for Jessie that was always trying Stole metal parts of the TR vehicles or the collection of James bottle tapas.
