To me, Soji seems a cross (PUN INTENDED!) of Sawyer, Clemont and a bit of Gary (post-defeat on Johto where he quits the trainer gig to become a professor) already.
Soji being a mix of Clemont and post-Johto Gary I can see because of the whole professor design but Sawyer? Honestly, the only thing I see the between the two is color scheme and twig arms and legs.
