Genuinely I think a core issue with Detco is that for any weakness Conan has, Gosho Aoyama gives him an out.

As hilarious as knocking Kogoro out, stealing his identity, and damaging his mental health is....I just think it'd be so much more interesting and fun if Shinichi truly had to work around being seen as a child. The episodes where he has to give Kogoro hints instead of stealing the show are some of my fav Kogoro moments. Or he could push culprits to confess instead
