What if the Detective Boys find out that Conan is really Shinichi? How do you think that's going to go down?
Maybe something like this? they would definitely notice that and get more and more suspicious about it. They would wait for him to tell them though, there must be a reason to keep this a secret after all.

I decided to go one step further and use my colorizations as a template. I also inverted Shinichi and Kid’s symbols, as clubs make more sense for Kaito and Spades has been linked to Shinichi for quite some time. Hakuba and Hattori keep the same symbols as they were quite fitting. ^^
